[ubuntu-mythtv] Minimum installation requirements details

[Mario Limonciello]

Steve Ellis from OpenMedia was wondering about the minimum required size and
RAM to install for a Frontend.  He was intending on installing onto a flash
based device.

Hard Drive Size
Frontend
Previously, I quoted him at just shy of a gigabyte, ~945 megabytes.  This
was with all mythtv plugins removed, no hdhomerun, no xmltv, no proprietary
drivers, no themes.

I was just thinking about this, and I realized that quote wasn't accurate.
Still there was room to be freed up via the removal of the media playback
applications that are installed.  At a minimum, another 50 mb can be freed
by taking off mplayer, xine, and vlc.  This doesn't include dependencies
that can be autoremoved.  I'd expect this can probably be shrunk even
further down after taking those off.

Full Install
A full installation typically weighs in around 1.5 GB.   This means that an
install could be done entirely to compact flash if the user opts to mount
/var elsewhere.  Rather than mounting /var/lib, mounting /var will make sure
that all logs are put there as well to help increase the life of the drive.

Memory
The amount of memory required really isn't as large as you would expect.
Looking at the requirements for a standard Gutsy disk, it's a minimum of 320
mb for installation off a live disk.  I suspect our requirement is
significantly lower than that because we don't have all of those gnome
services that we are running at bootup.

After installation, it appears that the Xfce env / xorg combination is only
using ~60mb.  Xfce/xorg/mythfrontend uses around 75 idling.  This will
probably go up as larger themes are used.  Knowing this, low power machines
(think epia or via) should be feasible still.
