It immediately made me think about CRIU - Checkpoint / Restore in Userspace [1], which needs to be able to restore a process with the same PID as when the checkpoint is taken. When restoring, if a process already has this PID, restoring fails.

- touisteur 7y agoMore and more I wonder if the future of criu isn't all namespaces...
- jraph 7y agoThey do advise using namespaces, and one of their main use cases is indeed docker container migration.
- touisteur 7y agoThanks for the info. Do you know where to find recent news and follow the progress of the criu project?
- jraph 7y agoSorry, I just noticed your comment. Upvoting you, hoping that you will notice mine. Unfortunately I don't know anything specific, I haven't followed CRIU. I noticed they did a number of releases during the last years, since I needed to compile CRIU for work. I would take a look at their website [1], it seems to list recent events and they have a mailing list. [1] https://criu.org/Main_Page https://criu.org/Main_Page
