    Just so your aware of what has been done and where we are at here's
    a summary.

    Karel has done quite a bit of work on libmount (at this stage it's
    getting hold of the mount information, aka. fsinfo()) and most of
    what I have done is included in that too which you can see in Karel's
    repo above). You can see a couple of bug fixes and a little bit of
    new code present in my repo which hasn't been sent over to Karel

    This infrastructure is essential before notifications work is started
    which is where we will see the most improvement.

    It turns out that while systemd uses libmount it has it's own
    notifications handling sub-system as it deals with several event
    types, not just mount information, in the same area. So, unfortunately,
    changes will need to be made there as well as in libmount, more so
    than the trivial changes to use fsinfo() via libmount.

    That's where we are at the moment and I will get back to it once
    I've dealt with a few things I postponed to work on libmount.

    If you would like a more detailed account of what we have found I
    can provide that too.

    Is there anything else you would like from me or Karel?
