The pithy ruminations from Rich Freeman on 
<[PLUG] Linux EMC and Headless Systems> were:
=> There was some discussion after last night's meeting about getting

I missed the original discussion, so this may be off-target...but is
the issue with a minimal install, a headless system, or both?

There's nothing to prevent installing X on a headless system, and Xvfb
provides a way (albeit somewhat clumsy) of running graphical apps on a
headless system with no graphical display (not tunneling X11 to another
machine for display on an X server).

Of course, this is far from a minimal install...

Ah. OK. The major issue seems to be with package-dependency-creep and
'minimal' installs...in that case, Xvfb may bring in way too many packges for
your comfort.
