You are still misunderstanding.  Using the storage groups the way
MythTV is designed allows you to put things wherever you want.  Just
move them to where you want them, then point the storage groups to
where they are.  That is the correct and simplest solution.  That is
the way MytTV is designed to work.  Things in MythTV are not designed
to have a single "root" directory, as that has far too many
limitations and problems.  The initial setup provided by the packages
is just so that MythTV will work when it is installed.  It is not
intended to be the way a real system is set up - it does not work well
as things scale up.

My system is way too big to have everything on one drive.  I have
seven recording drives and three video drives, for example.  That is
easy with storage groups - just add each new partition on each drive
as one entry in the appropriate storage groups.  I have two locations
where I store pictures - one for all my camera photos and one for
downloads.  They are on different drives, with an entry in the storage
group for each location.

In Ubuntu, the packages install the initial setup in /var/lib/mythtv,
as you have suggested.  But there is no need at all to keep things
there.  It seems that the packages you are using do it differently,
but there is still no need to keep using those locations.  Just put
things where ever *you* want them.
