UNIX on Atari ST or Commodore Amiga?

  With the advent of relatively cheap read-only storage (i.e the
CD ROM), wouldn't it now be practical to run UNIX on some of these
cheap-but-powerful personal computers that are coming down the pike?
  Supposedly a CD can hold about 550 megabytes, so it would be easy to
put the UNIX manual pages and system programs (kernel, ls, cat, yacc, etc.)
onto a CD (an audio CD now sells for about $15-$20, so bug-fixes and
upgrades shouldn't be expensive), then use a small hard-disk drive or
even one of the new fast mini-floppies for the rest of the system that
can't be put in ROM.
  Does anybody know if this is in the cards?

The main problem with the CD/ROM is that the worst case access time is
over 1 second. On second thought, perhaps its not such a problem people
used to a heavily loaded vax might see a performance improvement.
 
I am sure that someone, somewhere, is going to put some flavor of UNIX
on the new 68000 machines. Most of the people that are considering it
complain that the memory management on the ST/Amiga is too simple for
the kind of UNIX system they want. 

A good alternative for the ST might be OS-9 (level 1) which as far as I
can tell has all the things I like about UNIX, and the Amiga is supposed
to come with a multi tasking OS (called Intuition) built in.

The CD-ROM seeks fairly slow.  Add in the fact that the UNIX file system
is not notably fast and CD-ROM have limited use as OS disks.  However,
a staging of programs to a fast disk as they were used (sort of like
a UNIX Sticky bit) might be feasible.  It would be a fun hack.

Slow by comparison to a floppy?  As long as we're only talking about
using it for ROM storage of commands and documentation, that shouldn't
be a problem.  The transfer rate ought to be fine, it's just seek
that's slow.  For those purposes it shouldn't matter much if it takes
a couple of seconds to position itself.

The staging idea is good, though, especially if you're using a fast
disk for paging: the CD-ROM could pre-load a whole image to the
fast disk and then page in pieces as needed (Z-magic).
