There is also another way, to access all subversion revisions through a
filesystem.
I've written a filesystem for FUSE [1] (Linux and FreeBSD) that allows
mounting webdav resources. The filesystem is called wdfs [2] and can
mount generic webdav resources and offers a subversion mode, which
allows to access all revisions through a virtual directory again
containing one directory for each revision. Inside you can find the
files and dirs of the particular revision.
/virtual-dir/0/...
/virtual-dir/1/...
...
/virtual-dir/HEAD/...
If you enable SVNAutoversioning you'll get a versioning filesystem. :)
Give it a try! Bye, Jens

Well, i'd like a network filesystem with versioning.
And i think that one can hack webdav into becomming just that.

I don't think there is such a thing. NFS, as you say, is a network
filesystem; WebDAV (and SMB and AFP) are file sharing protocols, not
network filesystems, so they don't work the same way.

I was just looking for something like a regular network filesystem where
the sysadm mounts the share, and when people write their usernames
are mapped to a server identity, like NFS does.

It's possible to do so with the FUSE parameter "-o allow_other". You
pass this parameter so wdfs at mount time.
If you want to distinguish between the users you should use the Apache
authorization and let each user mount the filesystem itself. Then you
get logfile entries like this:

Does it work with multiple usernames? Such that if i as root mount it at
/data, then any user writting a file to that directory will result in
a subversion
entry with the same user ?
