It's worth noting that there are a selection of Linux filesystems that
do not suffer this problem. A little planning now might save a backup
and restore in the future...

(For the lazy, an incomplete list off of the top of my head: ReiserFS,
ext3 w/dir_index, and (possibly/probably) XFS. Others, too, I'd guess.

Hmmm, dir_index is an option that can be set with tune2fs. I'm sure it
only applies to new directories, but you could probably just create a
new directory, move the repo files, and then mv the new directory back
into place, avoiding the backup/restore cycle.)
