This probably is not in the kosher definition of HFS, but I
would note I tried the following experiment:

    Build an HFS 400kb disk (using option-initialize under 'Erase Disk')

    Install System 3.1.1, Finder 5.2, HardDisk 20 1.1a (off of the
    12/85 software supplement).

    Try to boot off of a Mac 512.

The result is Sad Mac code #F0064

It all works if the disk is non-HFS.  I presume the "HD20" patches don't
get installed soon enough in the boot process, and that HFS volumes can
be the boot disk only on a machine (e.g. Plus) with HFS in ROM.
