CRIU supports both direct (offset) and indirect AutoFS mount points migration.
However, there is a limitation in migrating of systemd services using AutoFS.
The root of
the limitation is that systemd saves AutoFS mount point device ID in its internals and compares saved value with current one on each AutoFS-related request from kernel side, and if they do not match, it ignores the request.
CRIU reconstructs AutoFS mount point on restore with different device ID, thus systemd doesn't recognize it anymore.
In user world it means that any access to AutoFS mount point served by systemd will stuck. Restart of the service solves this issue.
