Well, you have just listed some caveats which may go unnoticed for some
time by a newcomer. I was using 4.2 on linux on a local drive. I don't
compile subversion myself, I use the precompiled .rpm from subversion
homepage... so I suppose these have the dependencies right.

Maybe. My own stress test cases regularly make fail the BDB repository
but have no effect in the FSFS repository. Obviously my choice is
between using a proven wrong BDB or a FSFS with unknown bugs. Which
isn't really a choice since I'm obliged to use FSFS and hope that if
some FSFS nasty bug arises my backup is not too old.
Of course YMMV, but both my personal experience and my following of this
list for several months hint to avoid BDB. And now we have a new 4.3
release of BDB which has still less exposure than FSF.
So: In any case, backup often ;)
