Thanks for the pointer about Dragonfly, I'm not at all surprised that it has solid checkpointing, since its developers are definitely hard-metal types.
For my part, I treat my Docker files as my own little server-farm, and production is of course managed else-wise, so its all just an amusing analog of how things worked 'in the good old days' ..
Cryopid on Linux looked interesting for a while, but I guess its not really relevant as a feature in this age of hardware. In the good old days, it was necessary to checkpoint to get out of the way of the other jobs the computing facility had to perform .. endless tapes of checkpoints, hanging on the wall, waiting to be spooled, re-spooled, etc.
