Hi Adam,
If your footprint is not too large (e.g no X etc), another possibility
is to build a root filesystem compressed image (for your system) and
then boot the system as an initrd and run out of ramdisk. You will be
safe to pull power without shutting down.
To do this, you need to put the kernel that matches your compressed
rootfs modules in the usual place (e.g /boot/ramkernel) and then add
similar to following to your lilo.conf and re-run lilo.
image=/boot/ramkernel
label=ramsystem
ramdisk=8192 # depending on size
initrd=/boot/rootfs.gz
root=/dev/ram0
read-only
If your footprint is large, Cort's suggestion seems like the best
option.
Regards, Stuart
