[oi-dev] [developer] suspend/resume in Illumos

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.

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.

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).
