Description

Hello.
I don't remember when I started seeing this, but `df' doesn't show
the rootfs from inside jail, but any other mountpoints are visible.

  1. jls
    JID Hostname Path IPs
    1 j0 /home/j0 192.168.2.251
  2. jexec 1 df
    (nothing shows up)
  3. jexec 1 ls l /
    total 13946

I haven't noticed any other problem, just that rootfs doesn't show
the rootfs for the jail. I also tried setting up a faked /etc/fstab
in jail, but it had no effect.

Regards.
