| well, you should be able to use the fsfs baackend instead of the

Right. We use it here, but we've got some problems.
Debian Sarge kernel 2.6.9, OpenAFS 1.3.74-1 from the experimental source, and
subversion *** 1.1.3-1 0, Apache2 and libapache2-svn in the same version.
For every repository I setup another AFSvolume RW by everyone (don't know how to
~ let svn get tokens to write on that).
On first test setup I used an other version ob subversion (for hell, I don't
know the version or where I got it from, far ago). With that I setup the whole
with fsfs reps.
To set this in production I setup the above system and it works so far.
BUT If I setup a new rep with the above configuration in fsfs, and $user tries
to use it over apache2, subversion first hits errors:

[Wed Dec 22 12:02:13 2004] [error] [client 134.169.cx.xc] Could not fetch

db: Error string not specified yet  [500, #89022
]

But this is ONLY on the new created subs, and on a second or third retry, it
works without the errors.
I'm kinda helpless :-|
