     Yes, you should have ONE generic system folder on the disk,
bootable by either the SE or the Plus.  I do this fairly frequently,
although one machine is a Plus and the other a II.

     This is possible, but it is not a very good idea.  The only way
to tell the Mac which one of the system folders is the boot one is to
split up the System and Finder in the non-boot folder by putting one
in another folder.  I know people who do this, and they are forever
booting from the wrong folder, rearranging files, rebooting, and
making mistakes in the process.

     The generic system works fine on all Macs.

>Also, is it possible to create a 'hard link' in a HFS disk (a la UNIX)?

     Doesn't appear to be.  I don't think HFS supports that kind of
thing yet.
