[gentoo-amd64] initrd

[DR GM SEDDON]

Dear list,
I have just started using Gentoo and up-to-now am impressed.  I have 
generated a kernel using 'genkernel' and the kernel is in /boot.  
However, I do not have 'initrd' but 'initramfs'.  is this a problem or 
should I modify grub appropriately?
Gavin.

Possibly. I don't use an initrd at all and boot just fine, so it's
possible that you can skip the whole issue if you want to.

initrd/initramfs isn't normally needed for boot sequences where the kernel
has the drivers required to mount / builtin.  It's there, for cases such
as / on RAID, where some initial setup is required before the normal /
partition can be loaded.

Another case where initrd/initramfs is used, is for mainly binary
distributions, where all the various file system and disk drive interface
chipset drivers are compiled as kernel modules, rather than built-in. 
Obviously, if a module needed to load / is stored in /lib/modules on the /
partition, it won't be reachable, thus an initrd (the old solution) or
initramfs (the newer one) is configured, containing the modules and
configuration needed to mount the normal /.  (I say normal /, because an
initrd/initramfs functions as a temporary / file system while these things
are loaded, then a pivot_root is used to transfer to the normal /
partition, once it is mounted.)

Gentoo's genkernel creates an initrd/initramfs because it bases its
initial configuration on that of the liveCD, after the LiveCD has detected
your hardware and loaded the appropriate modules.  The LiveCD uses an
initrd so it can load modules as necessary, and also so it can pivot-root
off of the read-only temporary CD root, to a read/write ramdisk root
created and loaded with the necessary goodies uncompressed off the CD. 
Because genkernel bases its default setup on the one off the CD, it too
defaults to an initrd/initramfs, even tho most folks don't actually need
one, once they have a kernel with the drivers necessary to mount root
compiled in.

So, answering the original question, initramfs is the new version of
initrd, so no, you don't have to worry about it.  However, chances are,
unless you are running your / on RAID or something similarly exotic, you
don't need an initramfs either, if you have at minimum, the drivers
necessary to mount your / filesystem, compiled directly into the kernel,
not as modules.

I touched genkernel only once (when a friend used it, and it made a totally 
useless kernel) and from my experience it builds inadequate kernels.
Plus, if you are not using raid, any initrd/initramfs just adds time and 
overhead to your booting. It is a waste of ressources.
The only ones who 'need' it are distributions, who do want to use a 'one 
kernel fits all' approach and people with / on a raid/dm device.

Just build a kernel by yourself. It is easy.
make menuconfig
mount /boot
make all modules_install install 
and let grub.conf point to vmlinuz and vmlinuz.old.

The install run will create a vmlinuz link to your latest kernel and a 
vmlinuz.old link to the one used.

Not really, you can use initramfs in place of initrd. I have in grub.conf 
 
title=Gentoo Linux 2.6.13-r3 UDEV 
root (hd0,0) 
kernel /kernel-2.6.13-gentoo-r3 root=/dev/ram0 ramdisk=16384 init=/linuxrc 
real_root=/dev/sda2 vga=3847 udev 
initrd /initramfs-2.6.13-gentoo-r3

They're in / only on the boot partition ie they are in the root of  
(hd0,0).

If you are specifying your files as living in /boot on the boot  
partition then this could stop your system booting fully.

Perhaps you could post your grub.conf?

Re: [gentoo-amd64] initrd

[DR GM SEDDON]

my grub.conf:
' default 0
timeout     5
splashimage=(hd0.0)/grub/splash.xpm.gz

title=linux-2.6.13
root (hd0.0)
kernel /genkernel--x86_64-2.6.13-gentoo-r3 root=/dev/ram0  init=/linuxrc 
ramdisk-8193 real_root=/dev/hda3 udev
initrd /initrd'

I see hoew by saying root (hd0,0) leaves things relative to /boot.  But 
there is no linuxrc in /boot.  I think this is the prob.

The error code is 15. 
Thanks

I have the sameconfig and it works ok exept the name of /initrd I 
have /initramfs-genkernel-x86_64-2.6.13-gentoo-r3. Maybe that is the problem?

/linuxrc is in the initramfs thing so that's not the problem.

I wondered, should /boot be ext2?  Or should I use some of the 'default'

Thanks.
I looked at the url mentioned it tells me my error(15) is grub not 
finding my kernel.  How do I tell grub to boot my kernel from the 
command line?  It tells me the kernel needs to be loaded first.

Try replacing the kernel name with kernel-genkernel-x86_64-2.6.13-gentoo-r3, 
if that dosn't work show us the outpot of ls /boot.

This is my line for the boot partition:
/dev/hda1               /boot           auto            noauto,noatime,notail 
1 1
It's reiserFS I think. I used "auto" because I wasn't sure what to type for 
it.

Press e over the kernel you want to boot, then choose the line you want to 
edit and press e again. You can also use d to delete a line. There is 
instructions for more key bindings on the bottom of GRUB.

I've been using gentoo for 3 yrs now and using a grub.conf exactly as follows 
for all that time.  It has <never> failed to work.  I did not create 
the /boot dir with mkdir, that was done when I cp'd my bzImage 
from /usr/src/linux/arch/x86_64/boot/bzImage to /boot, and I did it that way 
because that's how the docs said to do it.

tbill@Shooter ~ $ cat /boot/grub/grub.conf
default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo (linux kernel 2.6.11-gentoo-r10)
root (hd0,0)
kernel (hd0,0)/boot/bzImage root=/dev/sda1

If you, when you installed gentoo in the first place, placed /boot in its own 
partition, then anything you copy to that partition is going to start with 
"/boot...".  How else are you going to tell the kernel to copy something to 
the boot partition when /boot is all you've mounted there?  If you, as root, 
tell the system to mount the partition where you've installed grub.conf, how 
else do you specify it except as "mount /boot".  I don't mean to belabor the 
point, but....

So tell grub to look on "(hd0,0)/boot/bzImage" for the kernel to boot, 
only,since you don't have a bzImage but a genkernel, change it accordingly: 
(hd0,0)/boot/genkernel-*.  I assure you that this <does not> "stop your 
system from booting fully."

Also, since you're getting error code 15, what you have in /etc/fstab is 
completely immaterial.  Grub can't even find your kernel, and grub's interest 
stops at finding the kernel, so take care of grub's errors first, then worry 
about whether your fstab is properly set up.

try "kernel (hd0,0)/boot/genkernel-* ...."  I think the kernel line,without 
the "(hd0,0)/boot" tells grub to look for something which doesn't exist, 
especially if /genkernel is in the /boot directory on (hd0,0).

I've notice that some ppl are putting udev on the kernel line.  I was
under the impression that this was not needed to get udev working?

Yep, initrd should point to the real initrd or initramfs file in /boot  !

Aso, why is this double dash in /genkernel--x86_64 ? Is it not a mistyping by
any chance ?

I have

/dev/sda1		/boot		ext3		noatime		1 1
/dev/sda2		/		reiserfs	noatime		0 0

and the rest are reiserfs. Do you, by the way, have reiserfs build into the
kernel or as a module ?

In kernel, but as I understand from this thread it dosn't matter since it's 
the point of initrd to make sure the modules are loaded. But that's not the 
problem as you need to access /boot before the kernel is loaded. And ext3 is 
almost the same as ext2 but with journaling as I understand it.

Actually, that reminds me that a year ago on amd64 architecture the compiled

I too have been on the amd64 platform since early last year, and am still 
using grub-static, although I know that grub now compiles fine for this 
platform (at least, that is what I've heard - I'm still using grub-static).  
But whether one uses grub or grub-static, the installed files are the same, 
and grub works the same regardless of which is chosen.  My grub.conf has not 
changed from when I was using Athlon XP's (although it's no longer called 
grub.lst).

I have tried installing lilo, it says it is masked.   So I emerged 
grub-static and found no differenc however I just remembered; do I need 
to do install-grub-static?  Finally, the system will not let me 
'--unmerge grub'.  How do I change grub?

Re: [gentoo-amd64] initrd

[Drake Donahue]

   Grub really does work. The problem you are having is that grub can't
find your kernel.

   May I suggest:

    Boot the gentoo install cd:

    At the prompt  -  livecd gentoo #  -  execute the following commands:

mount /dev/hda1 /mnt/gentoo/boot
cd /mnt/gentoo/boot
ls -l
ls kernel* initramfs*

    The output of  "mount /dev/hda1 /mnt/gentoo" will tell you about the
filesystem on the boot partition and should contain no surprises.
    The output of  "ls -l" is the boot file and directory structure that 
grub will
see if  "root (hd0,0)" is in grub.conf.
    The output of  "ls kernel* initramfs*" is the kernel name and the 
initramfs
name that need to appear in grub.conf.
    If a 'No such file or directory' error appears, the kernel and/or the 
initramfs
is not located in /mnt/gentoo/boot and thus is not in (hd0,0)/ as far as 
grub is
concerned. In this case look for a boot -->'something' symbolic link that 
points
 to 'something' as the kernel location. Most likely a boot directory will 
appear
in the "ls -l" output and you should look there for kernel and initramfs. If
mislocated, I think you should move them to /mnt/gentoo/boot and rerun
" ls kernel* initramfs* ".

    I believe that the " ls kernel* initramfs* " output you see will be
"kernel-2.6.13-gentoo-r3   initramfs-genkernel-amd64-2.6.13-gentoo-r3".

    In that case, I believe grub.conf should read:

default 0
timeout 5
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.13
root (hd0,0)
kernel /kernel-2.6.13-gentoo-r3 root=/dev/ram0 init=/linuxrc ramdisk=8192 
real_root=/dev/hda3 udev
initrd /initramfs-genkernel-amd64-2.6.13-gentoo-r3

    If  " ls kernel* initramfs* " produced other results, then "the other 
kernel name" must be
substituted exactly for 'kernel-2.6.13-gentoo-r3' above and "the other 
initramfs name" for
'initramfs-genkernel-amd64-2.6.13-gentoo-r3' above respectively. Don't lose 
the initial
slashes in the process.

    If you try this and it does not help, posting the results of the 
commands and the grub.conf
may get more help from the smarter than I multitude.

Re: [gentoo-amd64] initrd

[DR GM SEDDON]

Yes, I had missing the initial 'kernel-' from its definition in 
grub.conf.  It is down to me writing it on a pad with other stuff, I was 
ignoring the kernel word.  Extremely xorry.

Now it boots but asksme to
'specifya device to boot' it boots when I enter 'dev/hda3'.  It is 
specified in 'grub.conf' and 'fstab'.  Any ideas?

Also, I get 'dhcpd:required function  'interface _is_up' but networking 
isn't working.  And, I get 'netmount not started'.  Are these issues 
related.  Can you help?
Regards,
Gavin.

Re: [gentoo-amd64] initrd

[Drake Donahue]

    The entry:
"kernel /kernel-2.6.13-gentoo-r3 root=/dev/ram0 init=/linuxrc ramdisk=8192 
real_root=/dev/hda3 udev"
in grub.conf should be on one line -- sorry --
I see that it was split into two lines at the space between 8192 and 
real_root when it came back to me through the mail list handler and my mail 
client. Probably happened to you also. As " real_root=/dev/hda3 udev " are 
kernel arguments they need to be on the same line as "kernel".
This should solve the first problem.
Make the change above to grub.conf .
Reboot.

    I think the second problem is not related to the first. There is 
probably a problem with the network settings. Page 40 to 46 of the amd64 
gentoo handbook are a good start on the networking problem. Short summary 
follows. My best guess is that adding dhcpcd to rc is necessary and not 
documented.

    May I suggest (presuming your intent was to have the network mount 
automatically and you connect via ethernet):

Run the command:

dir /sbin/dh*

If the response is "/sbin/dhcpcd" then the dhcp client demon is installed. 
If "No such file or directory" error occurs, dhcpcd needs to be emerged. (Or 
you wanted to use some other dhcp client.)

Run the command: (modified if you wanted to use and have emerged some other 
dhcp client.)

rc-update add dhcpcd default

nano -w /etc/conf.d/hostname
        and
(Set the HOSTNAME variable to your hostname)
HOSTNAME="yourcomputername"

nano -w /etc/conf.d/domainname

(Set the DNSDOMAIN variable to your domain name)
DNSDOMAIN="yourhomenetworkname"rc-update add domainname defaultnano -w 
/etc/conf.d/net
 (should be blank or all lines commented)

Hi,
Yes, this worked for booting.

rc-update add net.rth0 default gave
'already installed in runlevel default'
and
/etc/init.d/net.eth0 start
'dhcpd:missing required function interface_is_up'

The final message is the same as vI receive when booting.

Triple check your networking config:
nano -w  /etc/conf.d/net

Read the documentation/examples in /etc/conf.d/net.example

All your problems are user errors and have nothing to do with amd64.
Are you sure Gentoo is the right distribution for you?

It is not needed, I believe, with new kernels. Remnants from the earlier 
days, in my case. I am still mostly on 2.6.11 kernel with devfs, actually, 
and am used to combinations udev+nodevfs, devfs+noudev (which had quite 
magical interactions between themselves, BTW)
