[gentoo-user] Problems with GRUB in the installation of Gentoo

[Gilberto Martins]

Sorry, folks.

This is to correct my wrong post, for I haven`t changed the subject.
Sorry for this, and thanks for Benno Schulenmberg, who kindly pointed
me this mistake, in PVT. Thanks Benno.

You meant /boot/grub/menu.conf (or /boot/grub/grub.conf)

Sorry, it was a typeing mistake, I have verified it here, and it is as
you corrected ...

...=(hd0,0)/....

And this was another mistake ... it is written (hd0,0)

It doesn't matter

That`s ok.

But it does not work yet ...   8(

I would not like to go back to LILO again ...

Once more, thanks for cooperating. I need help, and hope I can soon help others.

think this is a typo^, mine is:splashimage=(hd0,0)/grub/splash.xpm.gz

You are right, I did it wrong here. But the correct one is as you typed here.

> Concerning to Kernel name, does it must have a specific name format ?
> If yes, wich would be the name ?
No i don't think is *has* to be a fixed name, but most people comply to
some conventions (e.x. kernel-2.6.15-r3, gentoo-kernel-2.6.15-r4 etc.)
Using 'genkernel' so don't remember, check install guide if interested.
Check grub man page & guide as Grub has some strange naming conventions.

I tried not to use genkernel, for I did some changes in kernel. Can
any buddie confirm wich are the kernel file and others that must be
copied to \boot after compiling it in hand ?

Thanks for all help you are giving. I was in other list many years
ago, and left for I haven`t received help, but RTFM as answers. I just
came here after reading gentoo handbook and Grub Manual and many
relative docs.

Thanks for help.

It can be called anything, but the file name you give it in /boot, of
course, has to be the one you call out in the grub.conf line.  So, you copy
(for instance) arch/i386/boot/bzImage to /boot/kernel-kernelversion (I
usually also copy .config to /boot/config-kernelversion).

That`s what I thought. The ".config" tip, I wil do the same. What I
have to change in grub.conf ?

Okay, so you compile gentoo-sources.2.6.15-r4 (just as a made-up example).
So you copy arch/boot/bzImage to /boot/kernel-gentoo-2.6.15-r4, and copy
.config to /boot/config-gentoo-2.6.15-r4.  Then edit your
/boot/grub/grub.conf and copy the whole stanza that was already there,
including:
title  Linux-2.6.14-r2-2 win4lin enabled
root (hd0,0)
kernel /boot/kernel-2.6.14.2-w4l-2 root=/dev/hda2

Past it at the end.  Change the title line to match the name you gave on the
copy (Linux-2.6.15-r4), and the "kernel" line (/boot/kernel-2.6.15-r4).  At
the top of the file is the line:
default 0 (or whichever one is active).  Change the number to match the
stanza you just added (remember they are numbered from zero, not one).  Then
save the file.

I'm not really certain about this but isn't hdb in Linux syntax supposed to be 
equivalent to hd1 in Grub syntax? Have you tried root(hd1,0)?

You say /dev/hdB, and above (hd0,0). Therefore implying that there is no
 /dev/hdA in the system.  Is that correct ?  If not, and you do have a
hda device, the (hd0,0) is wrong and should probably be (hd1,0).
But in that case your BIOS will probably boot from hda anyway so grub
will never even be launched in the first place.  What lives on hda,
windows ?

You can trivially check this by running 'grub' and, within grub, say
'root (hd0,0)'. It should then reply by saying "Filesystem type is XXX"
where XXX is ext2 or ext3 or whatever you used. If it says something
like FAT or yields an error (Selected disk does not exist | No such
partition) you have the wrong mapping. Trying 'root (hd1,0)' will then
be more successful probably. However, your BIOS would still boot hda in
most cases, so you had better look into installing grub on /dev/hda (but
without breaking whatever lives on hda)
If you have no hda, or if hda is the CDrom, it may be prudent to change
the cabling so that linux is on the /dev/hda device.  Altough it is
possible to boot from the slave drive, but it is more straightforward to
boot from the master, and you may save yourself some headaches.

Ummm... isn't there supposed to be a system.map for the kernel as well?

I myself don't manually copy my kernels after compiling it; I use make
install to do so, and I have the following files in /boot for all my
kernels:

(ignore the 2.6.11.4-20a kernels, those are from my dual-boot SUSE install.)

In any case, for each available kernel, make install copies 3 files (and
makes 3 symlinks):

config-kernel.version
system.map-kernel.version
vmlinuz-kernel.version

the config file is just a convenience, but the vmlinuz and system.map
are, afaik, required to boot the kernel.

I don't know where system.map is copied from (the original compiled file
name), but if I was you (which I of course am not), I would cd to
/usr/src/linux and run make install to copy the kernel
files properly to boot, because I suspect this is not happening however
you're doing it.

Just my €0.02

I always copy do:
cp arch/i386/boot/bzImage /boot/kernel-version-gentoo-r?
cp System.map /boot/System.map-version-gentoo-r?
cp .config /boot/config-version-gentoo-r?

System.map is a memory map of the kernel. It is quite informative in that 
respect but it is certainly not necessary to boot. I just think it's 
interesting to have.

Well, that's my point, sort of... what exactly do you copy, and has that
file been copied to Gilberto's /boot folder? From my /boot listing
previously, you can see that even SUSE creates a system.map in the /boot
folder, and that's a precompiled kernel (so it's not like it's copying
manually or via make install). So I kinda suspect that it's a needed
file across all distros, whatever it may be called.... and, looking in
/usr/src/linux, it is a separate file from the bzImage file, which is
the actual compiled kernel. The fact that the make install command also
finds it necessary to copy this file from /usr/src/linux to /boot is not
to be sneezed at either, imo.

I see your point.  However, how critical can it be, if I have 10 versions of
kernels in /boot and in /boot/grub/grub.conf, and NEVER copied that file?
It gets created in /usr/src/linux-xxxx, but NOT in /boot.  And is not
referenced anywhere in my grub.conf.  If it's to be used, it needs to be
called on the kernel line of the grub.conf.  And I've got 30 gentoo servers
running, without a one having the system.map file copied.

AFAIK system.map is not needed for lilo and not for grub. I don't have
it and all works without any errors or warnings about it.

http://www.google.com/linux?hl=en&q=system.map&btnI

This is getting a bit off topic, however, what you can read from the above 
link is that there are programs which use System.map to resolve symbols from 
the kernel. It just lists the addresses of where in the memory symbols are 
located. But Grub certainly isn't one of those programs and unless you use 
one of those programs it really isn't necessary.

No, it's not OT, it was a question (is the absence of system.map in
Gilberto's /boot folder possibly relevant to the problems booting the
kernel?)
which you, among others, have answered (No).

That's amazing, and that's what I am telling my wife as I read (with
her) all this messages, and show her how important is that we support
Free Software. The need of knowing more, by teaching the "newbies".
Thanks for all interest of each one who helped.

Yes, I have a CDROM as /dev/hda, and I really thought it would bring
me some troubles. Of course I can change it. But, I know (as you also
said) it is possible to boot from a slave hard disk. I haven't tested,
but it is like a poor solution, for I wouldn't be learning. I honestly
am almost considering going back to LILO and try after, but that would
not be learning.


Holly Bostick:

"Ummm... isn't there supposed to be a system.map for the kernel as well?"

Yes, I think. Should I hen modificate grub config file, as in LILO ?
if yes, how and where to make this change ?
In addition, there is a very good article about the topic "system.map"
in http://www.dirac.org/linux/system.map/. Mostly for debugging. also,
the command "ps" make some use of it.

Most modern BIOS have the option to boot from a lot of devices, you
can check if your BIOS have options to boot from hd1, or primary
slave, whatever your BIOS call it, just enter the SETUP and check for
it.

LILO won't help you, you're installing the boot loader in a slave
disk, whatever you do, your BIOS will still call for the master (in
most cases), check your grub config twice, change it for the slave
drive (hd(1,0)?!) and change your BIOS to boot from the slave...

Or, better, change the slave/master jumpers to a config where your HD
is the master, OR EVEN BETTER, make it so your CD/DVD drives go at the
secondary IDE (if your're using IDE, I suppose so from your posts).
When different drives with different speeds are in the same IDE one
may interfer and even slow down performance of the other.

Yeah, it is already configured to start the first Hard Disk.

I really haven't checked for it, but i did "emerge lilo" to have a try
at lilo, anyway. After that, I "emerge --unmerge grub" it. Hope I
haven't done something too wrong.

Finally, I did:

cd /usr/src/linux
make install



After that, I had the folowing "/boot" content:

# cd /boot
# file *

Now, after rebooting, it really went straight, with text menu. It
starts loading really fast the system,but all of a sudden, a "Kernel
Panic" says:

Warning - Unable to open an initial console
Kernel panic - not suncing: No init found. Try passing init= option to kernel



Which "init=" I should use ? the problem is the lack of a "initrd"
file ? I tried to read mkinitrd man page, but I guess this does not
apply.

This is the lilo.conf.

boot = /dev/hdb

        label = Gentoo
        read-only # read-only for checking



I adapted it from sample file. I can see that :
1) there was something missin in grub conf file;
2) I need to study a little bit more ...  8(

You're pointing the kernel to hdb1 as the system root partition. I bet
money hdb1 isn't; it's /boot. So point it to the hdb[2|3|4|...] which is
your main / partition, and all will be well.

So good I haven't bet, for I'd loose.  8)
Making this change solved the problem. Seems that grub works, but
there is something I am not doing the right way.

Make sure that /etc/fstab has the correct devices/fs for each partition.
Usual error is that people leave it with the default entry e.g.
/dev/ROOT instead of the correct /dev/hdb3 in your case.

Also, check if you have chosen reiserfs and have not selected this as a
*built-in* option in your kernel (not a module).  The default kernel
config does not select reiserfs.

This message usually means you are missing /dev/console on your root filesystem.

Boot from the live CD, mount your root, and do:

cp -a /dev/console /dev/null /dev/zero /mnt/gentoo/dev/

That warning, yes.
But the error right after that means what it says: No init found, ie. it
has mounted a filesystem (else you get another error-: Kernel panic -
cannot mount root partition) but it is unable to find 'init' there.

You are right. I pointed it to hdb1 and not to hdb3. It is working.

Not likely to happen during installation, but if you use udev, the
device nodes may not exist in your backups (depending upon how you do
your backups...).  So a restore of a backup of your root filesystem
from a crash recovery or live CD may not restore any device nodes to
your root filesystem.

Anyway, ignore my message...I didn't quite understand that the problem
was resolved.

  . . or, on a multipartition installation they've missed out some
rather important directory which needs to be in / for it to boot, like
e.g. /sbin.

Well, I am not using udev. It is a install from scratch. So there is no backup.

No way, pal. Now I will read about udev, and see if I can get some

hey, gilberto, how about the grub trouble?

use udev, check this out:

have you heard of RR4? is a live dvd distro based on gentoo:

make install does exactly the same, and sets up the vmlinuz and
vmlinuz.old symlinks to point to your new and previous kernel
respectively, so you don't need to edit grub.conf.

Hmm, it doesn't on my two boxen.  :-(  I do not have a vmlinuz,
System.map and config links.

Do I have to first set up the symlinks manually?

Now we are at it is there someone who is willing to explain to me how make 
install works (I do know make i.e the basics)? I mean looking in the Makefile 
I don't see any directives as to how to make install...

Looking as /sbin/installkernel, it doesn't appear that you have to create
the links. Of course, you do have to make sure /boot is mounted first :)

Yep, /boot is always mounted (just to be sure I won't forget it, I
always mount it before I even cd into /usr/src/linux).  Running make &&
make modules_install does *not* create any links in my /boot directory,
ever.  Could it be that there's something wrong with my system(s) - at
least three installations have always behaved like this . . .

No, make makes the bzImage under /usr/src/linux.....arch/.....boot
And make modules_install installes the modules in /lib, I think.  Neither of
them touches /boot.  I THINK there's a make install that's supposed to do
some stuff for you, but I prefer to do those steps by hand.

Neither make nor make modules_install is *supposed* to create any links
in your /boot directory.

Make compiles the kernel and static modules, make modules_install
compiles the dynamic modules and installs them in
/lib/modules/<kernel-version/<wherever_they_belong>.

This is why you then have to either copy the compiled kernel (and
supplemental files like .config and system.map, if you want) to /boot.
make install (which is a different command than make modules_install)
does this automatically, and additionally makes symlinks called vmlinuz
and vmlinuz.old (if a previous kernel exists), and updates lilo (if
available). If you use grub, if grub.conf is set to load vmlinuz as the
current kernel, and vmlinuz.old as the previous kernel, you don't then
have to update grub in any way when you have used make install to
install your newly-compiled kernel, because make install changes the
symlink for the previous kernel to vmlinuz.old, and makes the symlink
for the newly installed kernel vmlinuz. Kernels older than the current
and most-recent-previous can be added manually to the menu directly.

My impression is that you haven't yet run make install.

HTH,
Holly

That's because you are not running make install. make modules_install
installs the modules, make install installs the kernel. You need

    make && make modules_install && make install

I am confused:  how many 'make install's are there?  Don't they 'all' do the
same?  Are we talking about a customised (hacked) make install here?

I have no idea; I've never used genkernel, and am unlikely to ever do
so. Since it is a mostly automated process (though you can use some sort
of switch to go to a manual menuconfig), I suppose it would compile and
install the kernel to /boot as part of its functioning, but I have no
idea what it actually does, or how to make it do what it does.

Yes, if you want, if you use it with --install it will copy the latest
kernel, map and initrd to /boot... I only use genkernel, but of course
with --menuconfig.

There is only one make install. It is the optional command out of the
set of commands used to compile and install a kernel:

make (which now includes make modules, whereas under 2.4-series kernels
you had to run make modules as a separate command) -- compiles the
kernel and modules

make modules_install -- installs dynamic (loadable) modules to
/lib/modules/<kernel-version>/

and you can then either copy the kernel manually to /boot, or use the
make install command to do so.

This functionality is not in any way a hack:

equery belongs /sbin/installkernel
[ Searching for file(s) /sbin/installkernel in *... ]
sys-apps/debianutils-2.15 (/sbin/installkernel)

Programs That Depend On debianutils
app-admin/sysklogd
app-portage/gentoolkit
app-text/noweb
dev-util/bazaar
dev-util/larch
dev-util/pbuilder
dev-util/tla
mail-filter/clamassassin
sys-apps/apmd
sys-boot/arcboot
x11-misc/sux
x11-wm/fvwm

And it's not in my world file, so it was probably installed by
gentoolkit or sux, which are the only two RDEPENDS of this list I have
installed (other than fvwm, but that's recent and I'm sure that I had
the ability to make install long before that). So I suppose it's possible
that some users might not have this, unless it's part of system, which I
don't know how to check.

But any utility ported from Debian certainly can't be considered a hack
by any stretch of the imagination

It seems that my previous message crossed in the post with this one and the
one from Neil.  I didn't know of the make install command, but thanks to
your previous and this posts I now know quite a lot about it.  :)

Next time I compile a kernel I'll try it out.  I guess that's a good way as
any to find out if it works on my system?

Install is a target to make.  Install_modules is a target to make.  What's
confusing?  Make is a command.  Install or install_modules, or install_docs
(for other things) are targets in the Makefile.

It's part of system.

I suspected that (since it would be eminently logical for the package
that provides the 'make install' command to be on the system by
default), but as I said in an unquoted part of that mail I don't know
how to check what's in system.

Is there another way to get a list of packages that comprise the system
profile (other than just trying to unmerge one and getting a warning)?

You could look at the packages files in the directory linked to
by /etc/make.profile and its parents. Or you could do emerge -pe system

$ emerge -pe system | grep debian
[ebuild  N    ] sys-apps/debianutils-2.15
