I don't think so, but it wouldn't be difficult -- you'd just set a
per-inode flag on whether to compress, and if it's set on a directory
then it's inherited by the files in that directory.
I think the hold up has been that we've waited for a *generic*
cross-filesystem flag to appear, and it hasn't (or it has and I didn't
notice). Does anyone have suggestions on how to break the deadlock
there?
- Chris.
