The suggestion wasn't that you teach svn how to change the OS's fs
settinsg, it was that you investigate how solutions at the OS level
compare to the other approaches already suggested (custom format -based
and sqlite-based pristine store).

In short: if 'mount -o compress=yes' provides 90% space savings then we
would have little reason to implement space-saving solutions in svn itself.
But it's the user's, not svn's, responsibility to run that.
