CRIU β

Integration

CRIU is not so easy to be used as a standalone tool -- it works best integrated into other software. This page lists such software and provides details about the current status.

ShellEdit

Status: not started

It would be nice to have bash (or other shell) to launch criu with --restore-sibling option and get new kid processes from it. Right now we workaround it with "shell jobs".

SystemdEdit

Status: not started

Adrian suggested that migrating processes from one system to another works, depending on the process, pretty good. Migrating a process under systemd's control might be possible by just killing the process on the source side but it cannot become a child process of systemd on the destination of the migration without systemd knowing how to restore a process and thus making it a child process of systemd (--restore-sibling).
