Running chroot off mounted image?
OK, if I make a mounted image...
...and copied chrooted apache to it, and ran chroot on it, would this be anymore/less secure then just running it chrooted off of the root fs? Also, running off the loop, would I take a performance hit? I don't have much ram available. I got thinking about this last night and realized that this would be make backups and restoring a snap (copy the image and then mount the copy).
dd if=/dev/zero of=apacheimage bs=1M count=100
mke2fs -m 0 -F apacheimage
mount -t ext2 -o loop apacheimage /chroot/apache
