For lot of emulated systems (RT-11 vXX, UNIX vXX so on)
I have scripts that copy disk image to user's TMPDIR, for example:
#!/bin/sh
echo 'type "unix" first, login as root'
cp /usr/contrib/sim/unix_v5_rk.dsk ${TMPDIR}/unix5-$$
echo "set cpu 18b" > ${TMPDIR}/unix5-$$-c
echo "att rk0 ${TMPDIR}/unix5-$$" >> ${TMPDIR}/unix5-$$-c
echo "boot rk" >> ${TMPDIR}/unix5-$$-c
exec nice -5 pdp11 ${TMPDIR}/unix5-$$-c
(and deleted (ports/sysutils/) runs on every user's TMPDIR)
It is impossible to share single image disk between
user's emulators for sanity.
I don't know about net functions of ITS.
Is it possible to start emulator as daemon
and let users login in it via telnet?
If so, then unmodified image must be kept
in /usr/local/ hierarhy and start script
must copy image to some nonclearing in
reboot directory if absent or use ...
sorry, my English is bad:
itstmpdir="${TMPDIR}" # some dir in /tmp or /var hierarhy not cleared in reboot
if [ ! -w ${itstmpdir}/image ]; then
cp /usr/local/..../image ${itstmpdir}/image # Exact path there
chmod u+w ${itstmpdir}/image
fi
and use this image for daemonised emulator
