[gentoo-user] Mounting /dev from udev ... [oops]

[gentoo-user] Mounting /dev from udev ... [oops]

[maxim wexler]

Hi group,

Got the above error on first reboot of fresh system.

Only link to this particular error in google is from a
German site which I can't read.

(none)/# dmesg|tail reveals

<...>
VFS: Mounted root (reiserfs filesystem) readonly
Freeing unused kernel memory: 128k freed
NET: Registered protocol family 1

This is a very basic system. Only device is a 3Com
card requiring the 3c59x module which is in
/etc/modules.autoload.d/*6. The card works OK. From
the troubleshoot console I was able to set it up
manually. And my /etc/conf.d/net file consists of one
line:

config_eth0=( "192.168.0.3/24" )

Using 2.6.12-r6 kernel on Pentium III.

FWIW.

hmmm, just noticed I can't use ctl-alt-del. Does
nothing. 

#reboot and #shutdown result in:

/dev/initctl: No such file or directory
init: /dev/initctl: No such file or directory

Is this because I'm in the troubleshoot console,
(none)/# ? 

-mw

Dude, your kernel is really old.  We're on 2.6.19 or 2.6.20 right now.
There were significant updates and bugfixes.  Youve got to update your
system.  Why on earth is a new install getting 2.6.12?

No, it's because those entries in /dev don't exist because /dev wasn't
mounted.  Sync your portatge tree, and then upgrade your kernel and
udev, and then the rest of your system, and things should behave sanely.

Good luck,

So what? The Pentium III is older that the software.

I don't need all the bells and whistles. Don't need X
or gnome or even a mouse. 

Also, upgrades are difficult here in the boonies.
Modem speed is approx 28k.

I got newer software on the working PC, 2.6.16, So
it's not exactly bleeding edge but it works fine.

I could transfer the newer stuff with ssh but that
doesn't seem to be working either.

Same speed here.  :-(  I feel your pain.  Two things if you have a newer
box somewhere, http-replicator and rsync.  I have three boxes and use
that to share the source tarballs and sync from. 

Poor us.  We both need DSL.

Maxim, things have move on in many basic ways - one of which is that devices 
are automounted these days using udevd.  If your system is not up to date 
across the piece, some software will no doubt will complain with whatever is 
left behind.  The fact that you are running a slim install means that you 
lasted this long on e.g. a really old kernel.

Since dial up is inadequate to readily keep up to date and if you have more 
than one machine seriously painful, you may also want to consider boa for 
sharing your distfiles across your LAN:

but ... the isn't working properly.  If I were attempting to make your
processor work differently, I would concede the point.  But there's
many more requirements for a kernel than just supporting the processor
and other hardware.  It also has to support software, namely in this
case udev.  Not having proper udev support could certainly cause the
problems we're seeing here, don't you think?

I'm kind of a minimalist too.  _My_ laptop is a Pentium 166.
Nevertheless, I try to keep it up to date.  2.6.12 was a long
time ago -- http://kerneltrap.org/node/5308 dates it at about 20+ months
old, being from late june 2005.

I feel your pain.  I was on dialup for a long time.   I was actually
running a 2.4 kernel 8 months or so ago, and that was really outdated.
Getting it up to date was a real pain, and I wish I would have saved
myself the hassle and updated it regularly.  That was a learning
experience; )

Probably a similar problem.  Udev would be responsible for creating
network devices such as eth0 based on

I agree that you never really need the latest and greatest.  That's
especially true for hardware when you run gentoo.  But software changes
quickly, unlike hardware, and is constantly improving.  You don't
necessarily get bells and whistles, you get bug fixes and performance
enhancements as well.  Bells and whistles can be left out of the kernel
easily enough.  I guess you could count udev as a bell or whistle, in
which case you could always manage a static /dev by hand.  I don't know
how to do this, or I probably would on my laptop.  

Good luck with your /dev problems, and may the solutions be swift and
painless ; )

Thanks Dan. As it happens I went ahead and did a sync
followed by a deep portage update followed by deep
world update. Avg. download speed ~ 2.9k/s. Took about
36hrs. Phew! Thankfully there was only 61 pkges to do.

Now I'm looking for advice on setting up udev. A
message in one of the logs says to be sure and start
udev on boot but there's no such thing in the
/etc/init scripts.

As it so happens, I dug up 
http://www.gentoo.org/doc/en/udev-guide.xml
for someone on the forums having udev problems.  You simply need to
check for some pretty standard kernel options:
|General setup --->
|  [*] Support for hot-pluggable devices
|
|File systems --->
|  Pseudo filesystems --->
|    [*] /proc file system support
|    [*] Virtual memory file system support (former shm fs)
You probably want to build a 2.6.18, at least, kernel when you do this
to update while you're at it, but i think 2.6.12 will work with udev
too.  You want to make sure _not_ to use devfs as udev replaces
devfs.  Then 
| emerge udev 
and you should be good to go -- no initscript necessary!  I have never
had to do anything else. Consult the afforementioned website if you have
difficulties.  

Hope that gets things going !!! 

May your luck outlast your difficulties, 
  - Dan

Was udev compiled running the kernel in question? (Most probably not
needed, though)
Is kernel-headers matching that kernel version? That would probably be
an absolute requirement... It may be a lower version than the running
kernel, but things will fail miserably if it's a higher version.

Well, Googling for the email's subject as a phrase did reveal ...
nothing. At least I could have translated the message if I was able to
get there...

That's because you're in the emergency console and there is no "init"
running. In order to halt/restart you need to add the "-f" flag. Beware
that you should unmount/remount r/o your partitions before resetting.
I.e.:
# umount /some/manually/mounted/partition
# mount -o ro,remount /dev/device-in-use /mounted/partition/in/use
# sync
# reboot -f
