I've just tried this Live CD, which is Gentoo based, and put simply ...
it works.

I'm now looking at rolling a custom boot/setup CD, initrd and GRUB
install script for FC4t1.

SATA CD/DVD drives is still an ongoing issue, however. For now you will
need an IDE/SCSI optical drive to boot off, at least for the install.

This is the bit relevant to the devel list.

I believe it should be offered as a separate option, since this is all
still officially "unstable" - i.e. - a mini-CD for installing on
fakeraid systems. Thoughts?

The latter, I'm afraid. This is a matter for upstream - i.e. kernel dev.

Software raid is still the best way, IMHO, however - not for dual boot
systems on the same array - obviously. Especially in a small enclosure
where real estate for drives is limited. We definitely need the dmraid
option.

As you can see, I have the motivation, but unfortunately not much time.
My work overseas keeps me almost constantly occupied. IOW .. *help!!!*.
