Pete, the fact that you are using Ubuntu or any other Linux OS or LiveCD to install Gentoo would not cause the problem you are describing. Such a problem is related to the *correct* mounting of /mnt/gentoo, /proc and /dev before you chroot. To avoid typing errors it is best that you cut and paste commands from the Gentoo Installation Handbook and only edit any parameters that relate to your partitions. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

crw-rw-rw- 1 root root 1, 3 10. Jun 2010 /mnt/dev/null
Eh? You list /fixit/dev and get files in /mnt/dev, did you symlink
/fixit to /mnt?
I would have expected
ls -l /fixit/dev/{console,null}
crw--- 1 root root 5, 1 Jun 26 2010 /fixit/dev/console
crw-rw-rw- 1 root root 1, 3 Jun 26 2010 /fixit/dev/null
The warning message is stored in /etc/issue I believe. The gentoo init
scripts, put it there if /dev/null or /dev/console don't exist.
Once you are sure that that /dev/null and /dev/console are on your root
partition, you should find the original in /etc/issue.devfix, mine looks
like:
This is \n.\O (\s \m \r) \t
swap this with /etc/issue and reboot.
Re: [gentoo-user] why always display this when kernel start
so,i don't known what problem,but swap issue and issue.devfix,and
there no warning ...

[gentoo-user] why always display this when kernel start
when kernel start ,display this Your system seems to be missing critical device files in /dev ! Although you may be running udev or devfs, the root partition is missing these required files ! To rectify this situation, please do the following: mkdir /mnt/fixit mount --bind / /mnt/fixit cp -a /dev/* /mnt/fixit/dev/ umount /mnt/fixit rmdir /mnt/fixit You may refer to these instructions at /etc/issue. If you previously had an issue file, it has been backed up at /etc/issue.devfix. Once you've fixed your system, you will have to restore your old issue file in order to get rid of this warning. Thanks for using Gentoo ! :) http://bugs.gentoo.org/show_bug.cgi?id=40987 i have done: mkdir /mnt/fixit mount --bind / /mnt/fixit cp -a /dev/* /mnt/fixit/dev/ umount /mnt/fixit rmdir /mnt/fixit -- pete_doherty

Strange.
I think when I had forgotten to create the necessary items in /dev, the
system did not even come up. It needs at least console and null, and for
framebuffer stuff also tty1. So I have these:
weird ~ # ls -l /mnt/dev/
insgesamt 0
crw--- 1 root tty 5, 1 10. Jun 2010 console
crw-rw-rw- 1 root root 1, 3 10. Jun 2010 null
crw--- 1 root tty 4, 1 10. Jun 2010 tty1
The bug report has this, maybe this is your problem, too?
I just ran into this and managed to fix it with an extra step. The
problem was in changed permissions on /dev/null. ls -l /dev/null
gave crw-rw-rw- 1 root root 1, ... while /mnt/fixit/dev/null gave
crw-r--r-- 1 root root 19, ... In order to fix it I had to rm
/mnt/fixit/dev/null first, and then cp -a /dev/null /mnt/fixit/dev/null
as suggested.
I can't say I understand how this happens but now the computer boots
again.
I'd prefer to have only those in /dev, and not all the other stuff that udev
adds, but it shouldn't harm either.
How does your /fixit/dev/ look like? Are there any entries at all? Is
console and null there? Please show the output of this:
ls -l /fixit/dev | wc -l
ls -l /fixit/dev/{console,null}
I get this:
weird ~ # ls -l /fixit/dev | wc -l
4
weird ~ # ls -l /fixit/dev/{console,null}
crw--- 1 root tty 5, 1 10. Jun 2010 /mnt/dev/console
crw-rw-rw- 1 root root 1, 3 10. Jun 2010 /mnt/dev/null

Re: [gentoo-user] why always display this when kernel start
i did not follow the handbook,i install gentoo with ubuntu
but i sure i use the commend:
sudo mount /dev/sda10 /media/gentoo
sudo mount -t proc none /media/gentoo/proc
sudo mount -o bind /dev/ /media/gentoo/dev
and stage is
stage3-i686-20101109.tar.bz2
ls -l /fixit/dev/{console,null}
crw--- 1 root tty 5, 1 10. Jun 2010 /mnt/dev/console
crw-rw-rw- 1 root root 1, 3 10. Jun 2010 /mnt/dev/null
i have the same result
