Katerina Koukiou 488fc072a5 mount: resolve parent mount of symbolic link correctly
When using --root option in criu dump, when the mountpoint passed
contains a symbolic link, criu does not resolve its parent correctly.
e.g when passing --root /run/rootfs, dump finishes successfully;
but when /var/run/rootfs is passed, where /var/run is symbolic link to
/run it exits with error "New root and old root are the same".

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.
