What FreeBSD is this? I've run the v3 client under linux mode without bad
syscalls (just that silly pathmunging stuff that I need to renew the fight
over).
Perhaps you are running the backup as root while Fritz has a setuid
root program? In any case, please find attacked a patch that
implements setresuid. The patch is relative to 3.3 but should port
pretty easily to current.
Fritz, if this cures your problems, please drop me a note.
Cheers,
Björn
