RH 7.2, 7.3, 8.0, 9.0
FreeBSD 4.8, 4.9
FreeBSD 5.* (or so the FBSD users have reported - 5.1 / 5.2 are listed as supported)
Fedora is basically done, a few changes to the install script need doing, but possible..
RHE should be here soon also...
Once RHE and Fedora are officially released, I think debian may be next.
