The aliases "should" be restored. Hard links on a Unix system (preaching to
the choir is good for my sould, I can tell) are implemented as alias files
with a special flag so they are handled by the file system kernel routines.
Normal backups don't keep the flag.

You could test the dmg implementation easily enough on a small test disk
with hard links on it, and then tell us whether the hard links are preserved
on restoration. Alternatively, I am going up to 10.1 by the end of the week
and need to test out my own backup/wipe/restore solutions, so if you are
willing to wait a week or so, I can test Jim Cooper's useful research.
