Ok. Assuming that rcsysinit.d scripts are executed (and they are since
messages about mounting swap show up :) we have only 3 things that may
prevent udev from running.
1. sysfs is not mounted
2. there's no /sbin/udev
3. There's some stale /dev/.udev.tdb file
I'll check my system later today. You may check yours now :)

Well. I'm not sure I've understood your words "which I move to the first
HD of the target system". What do you mean by "move". Are you going to
reconnect the hard drive? Or you are going copy all data from one disk
The commands root(hd2,0) setup(hd2) initialize MBR of the /dev/hdc. I'm
not sure if it will be loaded, since by default the MBR of /dev/hda is
read. Anyway. Supposedly you reconnect your drive so that it becomes
first drive. Now you say that on this drive your linux partition is 3rd.
So in menu.lst you should say root (hd0,2) and not root (hd0,0).
Now, if your linux is on 3rd partition, then most likely your
/boot/grub/stage1 file is also located on that same partition. If it is
so, then your root(hd2,0) setup(hd2) would fail. Correct would be root
(hd2,2) setup (hd2)
