I'm sure it is, but I don't currently have a kfreebsd system
available myself.

The question I have is, is this reproducible without schroot.
e.g. can you reproduce the problem by:
- mounting linprocfs on /path/to/chroot/proc
- running "chroot /path/to/chroot"
- testing if it still fails

If this is the case, then it's most likely a linprocfs bug in
the kfreebsd kernel.

Also, what happens if you do a nullfs mount of the host /proc
onto /path/to/chroot?  Does it still fail in this case?


Thanks,
Roger
