HEAD: no rootfs in jail

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.

# jls

1       j0      /home/j0        192.168.2.251
# jexec 1 df
(nothing shows up)
# jexec 1 ls -l /

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.
