I have been having some repair problems on NetBSD also.  I've been working
on getting repairs working on Windows XP and have finally understood the
"pathname not leftmost".    That error message is not really that clear, but what
it means is that the path name you gave does not end in an object in conflict.
The code is looking for one of the special symbolic links that points to a FID.
If the code finds either something in conflict in the path or that the last element
of the path is not in conflict, then it gives the "pathname not leftmost".

I finally fixed that problem in Windows XP when I found an improper symbolic 
link lookup in the kernel.   So now Windows XP can repair.  This will be available
in the next release.

As for NetBSD, I suspect that there is a similar bug lurking.    I've been able to
reproduce the problem very easily.

doe[6]$ cfs markincon adir
        DANGER:   this meddles with the version vector and can trash the object

You must do "beginrepair" first
You must do "beginrepair" first
There is no repair session to end.

The following is on windows:

coda3[24]$ uname -a 
CYGWIN_NT-5.1 coda3 1.5.24(0.156/4/2) 2007-01-31 10:57 i686 Cygwin 
coda3[25]$ ls -l adir 
lrwxrwxrwx 1 Administrator None 43 Aug 30 08:41 adir -> 
coda3[26]$ repair adir /tmp/fix 
Directory repair session started

coda3[27]$ ls -l adir

I'll look into this problem today and see if I can fix it.
