Hi Ben,
message from Woody one of my developers:

I have corrected the patch below: :-)

It is EOPNOTSUPP, not EOPNOTSUP

Cheers,

I think the wrapping broke it.
Anyway, its only a one letter fix.

After applying that patch filesystem detection didn't break anymore, so 
thats great. However now it runs and just stop complaining it can't find 
a current mirror marker. I can't make it spit out anymore errors than 
that - it fs detection works, then it just says destination invalid, 
can't find current mirror.
The rdiff-backup-data dir is created and there is a log file and 
quoted.chars in there but no current mirror.
Is current mirror created at the begining or end of the backup?
we are testing by backing up win32 -> win32 local to local.
I think restores would work tho.
I will get back to you after testing
