I've just read something that may be causing my
problem with udev, and I would just like to confirm
this before I actually go ahead and do any changes.
Running "/proc/sys/kernel/hotplug" on my system prints
out "/bin/true", I've read that to change this you do
echo "/sbin/hotplug" > /proc/sys/kernel/hotplug.
But what I want to know is, is this the reason that my
linux system won't boot up when I try and use udev
with /dev as the udev_root. The reason that I ask is
because when I tested out udev using /udev as the
udev_root and my system started up, the hotplug demon
started up after the hard disks are mounted. And the
problem was that the /dev/hda device nodes (and
others) were not being created.
Thanks in advanced for any help.

what script do you use to start udev? is this the start_udev one?
when you use /udev : the entries are created? (do an ls don't assume
that they are created because no errors occurs)
are you mounting a /dev in fstab? (i know someone that did that...)

Yes all the enteries are created, I've learnt never to
assume

Nope I've checked my fstab many times and I don't
mount a dev.
When I do set the udev_root to /dev some devices get
created, like fd0 and a few others that I can't
remember.
But i'm wondering if where i'm starting udev in my
rc.sysinit is the problem. Just for your reference I
start it (and also mount sysfs) right after /proc gets
mounted (and yes I do mmount sysfs before I run
start_udev :) )

I remember having such trouble but this was because the udev script was
run twice...... but I can't remember exactly what was the causes and how
they disapeard.....
what I remember is that : I loged into the box, noticed that /dev wasn't
the right one (a fixed dev tree) so tried to rerun the script and only
get a partial /dev structure.... looking what was mounted told me that
/dev was mounted twice with ramfs..... maybe it can help :/

Thanks, I have to explore this possibility more when I
get home (they make me use Wind**s at work) :)
