Will a DB upgrade ever care that this location doesn't exist? Or can I get 
away with adjusting it in mythtv-setup before I ever start mythbackend?

I see two of my old locations in the 1264 (0.24-2) converted database:

  table 'storagegroup' field 'dirname'  (/recordings)

  table 'settings' 'RecordFilePrefix'   (/home/mythtv/video/recordings)
                   'MythArchiveTempDir' (/home/mythtv/tmp/)
                   'DVDRipLocation'     (/home/mythtv/tmp/)
                   'GalleryDir'         (/home/mythtv/rgam)
                   'MusicLocation'      (/home/mythtv/music)
                   'VideoStartupDir'    (/home/mythtv/video/videos)

If I can change these fields after conversion then my question is moot. 
Otherwise, will I have to make sure that /recordings and 
/home/mythtv/video/{recordings,video} exist before conversion?

I think I answered my own question though: the first conversion didn't 
care. The second one probably won't. But just in case anyone ever wonders 
like I did. I'm still assuming I can adjust everything with mythtv-setup 
before mythbackend ever starts.
