Solved it :) I have been trying for over an hour now so it is
possible that I forgot something I changed earlier tonight, but
I think this is the only thing I needed to get it working:
cd /etc
ln fstab mtab
Now backup/restore works fine, and I can even browse my FreeBSD!
The results of the browsing are unfortunately the contents of
/usr/compat/linux, not the FreeBSD contents. But everything directly
below / that doesn't have an equally named directory in /usr/compat/linux,
for example /export, is browseable with real FreeBSD content!
Here are my diffs for .util. I use .util from the A.04.00 release.
It would probably be nicer to keep the use of uname for getting ARCH
and OS_REV and instead changing the awk arguments, but this works:
$ diff .util .util.old
16c16
< ARCH=FreeBSD
---
> ARCH=`echo ${UNAME} | awk '{print $1}'`
