I think part of the problem may be that the source directory has
softlinks in it.

Setup: 

"zaphod" is a Gentoo Linux machine running kernel 2.4.20
"dell2" is a Windows 2000 machine with a spare FAT partition (I've done
this with NTFS too, and it appears to be the same)
I mount the partition from dell2 on zaphod and issue the following
commands:

# mount -t smbfs //dell2/backup -o username="xxx",password="xxx"
/backupy

# mkdir /backupy/zaphod
# rdiff-backup  -v7 --windows-mode /usr/local /backupy/zaphod/local

Every soft link on /usr/local seems to give an error (see later), but
the run ends with:
