I have serious concerns here as well, which is why I asked about caiman
pulling in bits of gnome.

I don't know about anybody else, but I regard the current memory minimum
as excessive. The 768M minimum for the developer edition ought to be
considered unacceptable.

The install has to run and complete for pretty well any install configuration
on systems with 512M memory. Why 512?  For one, it's a fairly common
configuration (particularly for those who might wish to reuse a not exactly
cutting edge system to try Solaris - think of systems that can't run Vista
as a target); for another, Sun still sell systems with 512M memory.

(The latter implies to me that, with a 5-year support life, that it should be
possible in 5 years time to install the then-current version of Solaris on
such a machine.)

I know that there is a trend - particularly over the last couple of years - for
considerable amounts of bloat to have crept in, but realistically 512M is a
lot of memory just to boot a machine and copy some files to a disk, so
we shouldn't have any difficulty in getting into 512M and ought to be able
to do much better.

Again, Sun are still selling 1GHz machines - indeed, recently introduced
new models at that speed. Sparc hardware tends to last forever, so we
are going to have to live with that level of performance (and early US-III
systems) for a long time to come. As for memory, 256 is probably a bit
on the low side but such a machine would still be useful in many contexts
so it ought to be possible, although the optimization point probably ought
to be 512.
