Hell, no. The first field is in principle impossible to parse unless
you know the fs type.
How about making a new file with sane format? From the very
beginning. E.g. mountpoint + ID + relative path + type + options,
where ID uniquely identifies superblock (e.g. numeric st_dev)
and backing device (if any) is sitting among the options...
To support NFS client performance statistics, I recently added
/proc/self/mountstats. That might be a place to add details about
--move and --bind mounts without changing the format of /proc/mounts.
