My gut instinct is that this isn’t that interesting – most everyone is running
illumos in either VMs, or in datacenter applications where
suspend/resume has little if any applicability.
While the work itself is probably interesting, and it may enable new
applications for illumos, the concern I’d have would be detraction from
other more pressing work, without any clear use cases for it.
I should point out that s/r isn't just for laptop bare-metal. It allows
for a running instance of an OS to be frozen in an orderly manner (rather
than a VM just pausing a guest, the guest suspends first). S4 opens a
different world of allowing said image to be more easily migrated, or
(since it has roots in CPR) opens quick-boot images (imagine getting an
OS fully booted in under 10 seconds).
That said, if someone (you?) wanted to spend cycles on this for personal
satisfaction, I hardly see any reason to discourage it, and I’m
fairly certain if the risks of the new code being introduced are small (or well
managed by sufficient testing for example), I can’t see any
other reason we would reject a suitably formed RTI.
Doubt I'll fully drop it, but without sufficient interest, it's is
unlikely I'll give it much priority (certainly, my other 'dropped' project
should have a higer priority).
Cheers!

Subject: [developer] suspend/resume in Illumos
I have a question for developers here:
How important is suspend/resume for OI/Illumos (including S4)?
One of the incomplete projects left behind was S4 (lack of need, and a
hard to identify bug stifled it's integration). It is non-trivial, and
needs updated s/r core code (added configuration and significant
restructuring, as well as likely assistance from developers knowlegable in
other Illumos internals), but if this is an uninteresting feature, it is
likey not worth the effort (recent bugs suggest that few if anyone use
it); however, it wouldn't be too hard to resurect (though would still take
several months of work).
Cheers!
