I understand the concerns. As I noted I've had not problems, but 
before switching to svn (and any new version) I do a full 
_additional_ backup (thank goodness for cheap disks), which I 
don't touch until I've used the new version for a while, poked 
around with files and monitored the results. Its not a perfect 
solution as it is an incomplete and informal process, granted. In 
addition I have the DVDs of originals.

Crap happens :-) In a previous life I maintained tape backups for 
a multiuser system using appropriate incrementals etc. I sure do 
prefer the ease and informality of multiple external disks, 
unison, and a remote server, for my personal use!

And here is the simple question for which I do not have a simple 
answer.. how to tell the svn digikam to use a different root. 

someone here should know?

A workaround would be to run the svn digikam as a different user.
