Not really, it should use the default user name that safe_mysqld uses for
spawning the recovery instance. Do the files and directories on the snapshot
belong to the "mysql" user as well? I wonder if the snapshot is mounted with
some strange flags. What does /proc/mounts say about this? How do the
ownerships of the files on the snapshot look like?

Indeed. However, it spawns the second MySQL instance using the wrapper
mysqld_safe, which usually takes care of setting the user.
