OK.  I could do the same, but it'd take longer to boot...

Ahh, ok.  That seems like it'd boot quicker.  I'm still a little bamboozled
by all this (not enough Linux experience really).

OK.  As an aside, I had a thought earlier whilst listening to the radio
earlier.  There was an advert reminding students to buy their TV licenses,
even in halls.  If all the students ran MythTV frontends from a single
backend, they could share a TV license.  Of course, IANAL, but it seems like
a loophole.
