i'm doing something similar using rsync to do backups and restores
(i did use dd but had to save space).
it's a boot cd, and on a restore it runs in "permissive" mode,
sets up the partitions on /target/, /target/boot, /target/var etc.
chroots to /target and then does a make -C /etc/selinux/src relabel.
that seems to "do the job".
i am certain that lots of people can come up with alternative schemes,
all of which will work "offline" where you have physical access to the
machine.
what i believe russell to be concerned about is that there _are_ so
many "alternative" schemes that people use [during live operation]
e.g. _yes_ people really do do "dd backups" usually at 3am on a cron
job to a spare disk.
therefore, making a decision about, how do we say "which
one(s)" - if at all - should go into the "strict" policy is
of some concern.
...if this was microsoft, you'd write your own backup program and then
lock the OS to that.
