There might be several same terminals opened (say tty6 or whatever) which gonna look as separate files but actually pointing to the same tty kernel instance. Moreover if it's a controlling terminal we will be trying to restore it as many times as find non zero sid on a peer. Instead lets do a simple trick first: choose a leader from a terminal group and use it only for controlling terminal restoration. https://jira.sw.ru/browse/PSBM-40969 Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Reviewed-by: Andrew Vagin <avagin@odin.com> Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
