Possible.  Though in this case, the link-from location (the root FS) has
a *tiny* amount of free space.  That is, it will always be smaller than
the 10GB threshold for free space.  So if MythTV was unaware of symlinks
in the way that you described, I would think that my symptoms would be
that auto-expire was happening more frequently than expected rather than
what I was seeing.   But I suppose it's probably a good idea to not rely
on symlinks in the first place.

Only somewhat related, and for the benefit of other folks here, I want
to mention that after running flush_deleted_recgroup.pl script,
MythFrontend would show an empty list of recordings.   But Mythweb
showed recordings as expected.   To fix this, I had to hit the menu
button, and then "Change group filter" and then select "Default" again.
 This re-populated the view and the recordings were there again.   I
suspect that flush_deleted_recgroup.pl removing recordings out from
underneath mythtv caused MythTV to get confused.  And even in a way that
a reboot did not rectify.
