There was one comment I almost added to my post - which was "I'd be a lot happier if the repo wasn't stored in a berkeley DB, or maybe just the metadata..". But then I figured I was being fussy, and I know how much cool stuff like transactions and atomicity you get for free with DB, so I left it out. That kind of recovery would definitely be a bitch though. I think my backup policy for subversion is going to be twofold. A hot backup (cp -a on the tree) and an endian-agnostic database dump :) Hehe, okay I’m with you there.

That machine was MSB, I had to move to an LSB machine. but to run the dump, I needed an MSB host, no other way around it. Thus I spent 24 hours trying to remember who I knew with an MSB machine, getting an account on there, and waiting (a considerable amount of time) for subversion, apr, neon, and berkelydb to run on it. rsyncing my entire repo to the host, running the dump, and rsyncing the data back. My point is that I tend to think that using an endian agnostic format for the repo would have been a damn good idea, and know first hand just how much of a pain in the ass it can be in disaster recovery if you have to move between ends for reasons beyond your control :) You are entirely correct on all counts, I was going for brevity :)

Sounds like you had a standard Berkeley DB portability problem to me, rather than anything specific to subversion..

Not sure <b>what</b> I'd commit, but still, it's theoretically possible! Maybe I'll spend my time enhancing pheh back to the level of feh... it's a cooler app anyway ;-) Ooooooh, I just realized if feh CVS is there now I can commit again!

From what I read the FSFS stuff fixes that, at the expense of using more space, and not being as reliable. What a fun choice. Why oh why can't they finish OpenCM already :( That looked nifty, then they rewrote it, then it looked nifty again, then they rewrote it. Wait, I've seen this pattern before...

Maybe it doesn't like it being a link, or (more likely), maybe nobody told pserver that /cvs is valid... I'd much rather something like anoncvssh was used though. (the thingy that acts a shell for a nonpriviledged account and does nothing other than allow anonymous cvs checkouts over ssh, I think the name is anoncvssh anyway, something like that :)) That explains a lot, I’ve never touched pserver.
