Has anyone used container encryption in a chroot jail where there are multiple jailed users (in different jails) and encryption is used on directories, container. I had setup dm-crypt but it relies on /dev/mapper which seems to be a problem for the chroot's users.
Any other ideas what might be useful to try here?
Haven't done it but chroot by its nature doesn't allow access to anything outside its directory. Do you have dev/mapper UNDER the chroot jail directory? You can find out major/minor of device by doing ls -l /dev/mapper then create mkdir JAILDIR/dev and mknod JAILDIR/mapper [cb] MAJ MIN.

Tried creating with mknode - also mount --bind - seems it always needs to make calls outside that it can't do (or needs to be root). Same problem using fuse/fusermount. It can't mount the drive as it needs to run as root apparently (not just for the mount)
