Got a gut feeling about that? i have the feeling that that will get into trouble :-), but im no expert here. If what you mean is: mount_unionfs /md-0 /jail-0 and then mount_unionfs /md-1 /jail-0/xyz which is not strickly 'stacked', might work and should be easy to try out, but IMHO, breaks the KISS principle :-) and also, im not sure if: mkdir /jail-0/xyz mount_unionfs /md-1 /jail-0/xyz is the same as the above. danny
