i'm thinking of doing installs of selinux systems and online
backups/restores from an initial ramdisk.
e.g. modifying rsync to cope with selinux file contexts.
e.g. there are several backup programs that create bootable CDs, that
then redo the entire system.
what would make sense is for rsync, star etc. to have a context-"chroot"
under which the selinux file contexts get recreated relative to that
directory as the root filesystem.
then i don't have to mess about ensuring that the entire filesystem
is correctly there and then doing something like this:
chroot /mnt-point make -C /etc/selinux/src relabel

setfiles has a -r rootpath option (contributed by the Gentoo folks) that
causes it to strip the specified rootpath prior to matching against
file_contexts. Or, if using matchpathcon() directly, you can always
have the caller strip the rootpath itself prior to invoking
matchpathcon().
