Union FS

[Francis GUDIN <fgudin@xxxxxxxxxxxxxxxx>]

Hello,

Is unionfs available at all ? Both ways I tried don't seem to work:
- mount -o union: the upper layer overrides totally the previous
  mount point's content (which is itself a RO nullfs mount, if this
  matters)
- mount_union yields "vfsload(union): No such file or directory"

The plan being to share a common (RO) underlying FS for my jails, and
add over it a writable overlay for each.
What's the common practice regarding jails'storage ?

Thank for your advice.

Best regards,
