The reason *we* don't do that: If you have to restore the filesystem
from backup. Depending on your backup technology, make sure that all
of those links won't become separate files (ours would).

We were unwilling to accept the risk of being unable to restore our
backup to a disk plant of the size it was taken from.  We also
couldn't come up with an easy (read inexpensive) way to calculate the
expansion factor.

Good Luck,
