[PXE + NFS-Root] No Permissions?!

Hi,
I just got a bunch of more or less old laptops with no hardware at all
but display and motherboard.
So I thought, that's the perfect excuse to see how this
network-boot-thing works.
After a few days now, I got a nice Kernel which is successfully loaded
over network, the nfs-root-directory is mounted (which is a
debootstrap-ped Debian Sarge directory) and booting sequence is
starting too.

Problem is: Some daemons or filescripts seem to have no permissions to
write on certain files (or devices for that matter).

== SNIP ==
Cleaning /tmprm: cannot remove `./fileZFvUAC: Operation not permitted
....
/etc/init.d/rcS: lime 97: /var/run/.clean: Permission denied
(imagine some more of that kind _here_)
== SNIP ==

This also makes syslogd, klogd, inetd, etc. pp. not start either.

Thing is, I exported that directory with permissions to write and I
mounted it in the parameter with `root=/dev/nfs rw', so it should be
mounted read/write, too. There's no way I could check that, for I
cannot even get to the login shell, because init says:
== SNIP ==
INIT: Id "1" respawning too fast: disabled for 5 minutes
....
INIT: Id "6" respawning too fast: disabled for 5 minutes
INIT: no more processes left in this runlevel
== SNIP ==

debootstrap of course made all the default device nodes in /dev of the
nfs-root-directory. I don't know if that was a good idea, but I also
don't know any alternative - and udev won't start either.
I'm really out of ideas here. Begging for help

I can this answer myself by now:
Even though "no_all_squash" is default in exporting with nfs, the
root-user seems to be squashed anyway. So I typed "no_root_squash"
manually, and the permission-errors disappeard.

Now, syslog and udev complain, about not beeing able to create
/dev-devices with the description "Adress family not supported by
protocol"
So, maybe you can help me out here.
