Diskless workstation probs

[Joe <joe_(_at_)_hole-in-the_(_dot_)_net>]

Hello all,

I have setup a diskless workstation using a DOS floppy and boot.com to
load the kernel. This then mounts / and swap via NFS from another
machine. Both machines are 2.3 (installed from the CD, thanx for the
stickers 8)

Unfortunately I keep getting errors on the diskless machine. Firstly
at boot time I get loads of messages of the following:

Cannot rm sshd.pid: Read only filesystem

Secondly vt220 emulation is weird. I keep getting unusual colours and
control characters all over the place.

Thirdly halt(8) or reboot(8) error and drop me to ddb with a umount
error on the / fs.

Fourthly (and finally) /dev/psm0 doesn't work with X. The cursor goes
mental whenever I try and use the mouse. I tried with /dev/psm0 and
/dev/pms0.

The system is /mainly/ usable (I'm running X on it atm) but it
occasionally barfs and locks up.

Server Config's follow:

/etc/bootparams:
warp     root=security:/export/warp/root \
         swap=security:/export/warp/swap
(Warp's root fs was created with pax -r -w -p e -X /usr /export/warp/root
and then the etc dir was configured)

/etc/exports:
/usr 194.217.241.115
/export/warp -maproot=root -alldirs 194.217.241.115

Any clues, hints, hits over the head from Theo with the appropriate
