I'm afraid I don't know what that means, but the install script should
only reference the install program, which should be a Unix standard
command and should have nothing to do with "find". Perhaps you have a
broken install script in your PATH?

Yes, that's excellent. You might like to disable Box Backup's own feature
that keeps old version of files, and use ZFS to do that instead (by being
able to take the repository back in time).

We deliberately compress quite small blocks in order to make it possible
to use an rsync-like algorithm on them. Perhaps we could do additional
compression on the server, but for 7% gain it doesn't sound that useful.

The error messages have been improved a lot in the current development
version, which I hope we will release soon. Did you get an exception
logged just before that, and if so what was the file and line number?
You could help us a lot by testing the latest trunk rather than using
0.10 which is very old. Have you read about the known problems with 0.10

Sorry, I know less about SMF files than you do, I have no idea how I would
do it or what I would want one for. If you do write one, please tell us
about it and we'll add it to the distribution of you agree.
