d3x73r,

There is a problem with current stage3 files. You need /dev/null, dev/zero and /dev/console.

boot your CD, moount your root at /mnt/gentoo, do not chroot. and look in /mnt/gentoo/dev
Check the files that are there are dev special files

NeddySeagoon : i have download stage3-amd64-20110526.tar.bz2
here's how it is now.

- /dev only have null device
- /etc/runlevels/sysinit only have dmesg & devfs (edit: fix path)

ok, so it lack some devices and it lack udev at sysinit, but it have openrc, so i suppose it have baselayout2/openrc, and the issue is /dev & missing udev in sysinit.

but all needed /dev are create by udev-mount
and udev-mount is a dependency requiere by udev.

To resume: it seems the only problem is missing udev at sysinit runlevel, as udev will call itself udev-mount that will create the missing /dev (shm, pts, null, console)

So the fix might just be as easy as adding udev to sysinit and let it do the work (or calling /etc/init.d/udev-mount by hands to let it create the missing /dev entries, i was thinking the stage was using baselayout1 and so the udev-mount cannot work on it, but it seems it's openrc/bl2 already in it)
I didn't test it, but this should works

d3x73r: can you just test that and gave result (it might still doesn't work, but report if error remain the same or not) ?
rc-update add udev sysinit

too late... I've aready formated my HD with no luck

indeed, the current stage3 has only null in his /dev.

before try NeddySeagoon solution I tried krinn's with no luck too. I added udev to sysinit, as he says but got the same message. Even I tried /etc/init.d/udev-moun manualy on chroot. It created a few files but when I reboot has the same error. I loaded Live-CD again and mounted system partition and when I did ld -al /dev, only null was there. :?:

I realy don't know what to do... This isn't my first gentoo installation, but I've never seen this before!

So I did created the files manualy and the sytem was able to boot as usual. Anyone else tryed?

d3x73r,

You can install from an April stage3 file, which will have baselaout1 and will match the handbook. However your will have to follow the baselaout upgrade guide. I suggest you do that explicity with
