Here is a script I use to swap onto a local hard disk
(/opt/ltsp/i386/etc/rc.d/hd_swap) for LTSP3.0
It is invoked with
RCFILE_01 = hd_swap
in lts.conf
Basically, it probes in the devices and tests for an existing linux swap
partition and swaps onto it. Otherwise it creates a file on a DOS partition and
swaps on that. If there is no disk it does nothing. It can be used on all
workstations. It assumes that linux swap partitions have been mkswap(ed).
You must copy fdisk into /opt/ltsp/i386/sbin from your main distribution though.
It is not normally distributed as part of LTSP.
