Well, here's a slightly contrary report -- I've installed 2.0_BETA
and upgraded to 2.0_RC4 using itself, i.e. self-hosted.  Dmesg from
my system, a Challenge S server (which I understand is basically an
Indy without the graphics) follows below.  The only problem I had
was that if I configure the hal audio, the boot will hang at that
point.  The rest has been smooth sailing.
