Three times in the past months I've tried to get udev up and
running without luck.  With the new kernel forcing the removal
of devfs, I'm trying the fourth time.

Current kernel is 2.6.12-r10.

Removed devfs automount but left it built into the kernel
(as described in Gentoo udev Guide).

Here's my grub.conf:

# /boot/grub/grub.conf:
timeout 30
default 0
splashimage=(hd0,0)/grub/splash.xpm.gz

# For booting Linux
title  Gentoo Latest
root (hd0,0)
kernel (hd0,0)/boot/vmlinuz root=/dev/sda3

# For booting Linux with udev
title Gentoo Latest with udev
root (hd0,0)
kernel (hd0,0)/boot/vmlinuz root=/dev/sda3 udev gentoo=nodevfs

# abridged other boot items...


I believe (according to the Gentoo udev Guide) that "Gentoo Latest"
ought to boot with udev.  It doesn't.  Instead it boots with devfs.
Note, both udevd and devfsd are running:

royw-gentoo tmp # ps -e | grep udev
  949 ?        00:00:00 udevd
royw-gentoo tmp # ps -e | grep devfs
 1127 ?        00:00:00 devfsd


The second item, "Gentoo Latest with udev", tries to force udev.
What happens is the kernel can't find either udev or devfs, gives
a 15 second warning, then continues to boot with nothing mounted
on /dev.

Here's my rc config file:

# /etc/conf.d/rc: Global config file for the Gentoo RC System
RC_TTY_NUMBER=11
RC_PARALLEL_STARTUP="no"
RC_NET_STRICT_CHECKING="no"
RC_VOLUME_ORDER="raid evms lvm dm"
RC_USE_FSTAB="no"
RC_USE_CONFIG_PROFILE="yes"
RC_FORCE_AUTO="no"
RC_DEVICES="auto"
RC_DEVICE_TARBALL="no"
RC_RETRY_KILL="yes"
RC_RETRY_TIMEOUT=1
RC_RETRY_COUNT=5
RC_FAIL_ON_ZOMBIE="no"
svcdir="/var/lib/init.d"
svcmount="no"
svcfstype="tmpfs"
svcsize=2048


Not sure if any other config files are used.

Any ideas?

TIA,
Roy
