Parent article: Checkpoint/restart tries to head towards the mainline

Perhaps of further interest is the description of Crash-only software by Valerie Henson (now Aurora). Software written with this paradigm in mind, combined with something like daemonitor or OpenRC tricks, can be used to build a system with a certain amount of resilience.

suspend/resume a system which is displaying X apps some of which are
running on another machine, without using some sort of proxying layer like
xpra.

It's likely to be tricky...
