Description Marc Dendooven 2005-04-06 14:19:17 UTC
Installation from the 2005.0 x86 life CD. I followed exactly the Gentoo Linux 2005.0 x86 Handbook. Except: Boot -> hda2 (prim. part ext2) Swap -> hda5 (log. part) Root -> hda6 (log part ext3)(Windows XP on hda1). I used the pentium4 files. (stage3).
I did not alter any options.
I used genkernel --udev all.

After reboot the procedure stops with:

>>Mounting filesystems
mount: mounting devfs on /dev failed: No such device
Error opening file: ".devfsd" No such file or directory

>>determining root device...
>>block device /dev/hda6 is not a valid root device
The root block device is unspecified or not detected
Please specify a device toboot, or "shell" for a shell

(PC is portable Fujitsu Siemens Amilo D series)

Reproducible: Always
Steps to Reproduce:
1.I re-installed from scratch 
2.same result
3.

Actual Results:

So your problem has nothing to do with the release media itself, but instead your booted system?

Also, the default genkernel config does not use udev, so that might be your issue as you won't have devfsd installed.
Comment 2 Chris Gianelloni (RETIRED) gentoo-dev 2005-04-06 15:00:48 UTC
Did you do this step?

zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config-2.6

If you did, then devfs should not have been used, at all.  It looks almost like you missed a step there.
Comment 3 Marc Dendooven 2005-04-06 15:17:57 UTC
The problem occurs after the first reboot, after ejecting the cd.

I did use 
zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config-2.6

and used genkernel --udev all (like the manual specifies)

This is the only place udev is mentioned in the manual. devfsd is never mentioned.  so i never specified it.

Comment 4 Marc Dendooven 2005-04-07 09:00:16 UTC
I solved the problem by:
1. emerge udev (don't know if this was nessecery)
2. adding kerneloption udev in grub.
