I found the meaning of comparing basename-s for mounts in mount_qual(), which was removed in v2.1-49-gbcf40bf. I think it was an attempt to detect siblings (propagated mounts). Actually it's wrong to compare only basenames for such mounts and we need to generate full paths for them. For example: 28 25 0:25 / /sys/fs/cgroup/devices rw shared:10 - cgroup cgroup rw,devices 29 28 0:49 / /sys/fs/cgroup/devices/101/xxx/yyy ... 38 35 0:25 /101 /sys/fs/cgroup/devices/ rw master:10 - cgroup cgroup rw,devices 39 38 0:49 / /sys/fs/cgroup/devices/xxx/yyy ... 28 and 38 are in the one shared group. 29 and 39 siblings and probably one of them was mounted and another one was propagated. This patch adds a function to generate a sibling mount point and use it to propagate mounts Signed-off-by: Andrew Vagin <avagin@virtuozzo.com> Signed-off-by: Pavel Emelyanov <xemul@virtuozzo.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.
Pages worth starting with are:
- Kernel configuration, compilation, etc
- A simple example of usage
- More sophisticated example with graphical app
