At one point I submitted patches which allowed arla to *compile* properly,
but it kernel panicked when loading the module. I suspect it was related
to changes in locking strategies between 5.x and 6.x. A few other people
on the arla-drinkers mailing list were able to patch the module a bit
further and it didn't panic at kldload (but did when trying to do any FS
operation). Those patches never made it into arla and AFAIK no one has
made any further progress. A coworker of mine was trying to apply those
patches to 7.x, thinking fbsd folks would be more willing to accept it.
I'm not sure how far he got.

I'm hoping there will be some takers. We use AFS at work on 5.x for
production and release engineering as well as backups. The OpenAFS server
works just fine in FreeBSD (because it's all userland) and the Arla client
seems to behave just fine on DragonFly, Mac OS X, and all other BSDs. In
FreeBSD, it's a wash.
