Are there any OSes out there that make it simple to install and automatically update a chrooted, full-featured apache install? I'm aware of how to do it in Gentoo and Ubuntu, and I've seen it done in FreeBSD, but I've never seen it done in a manner that allows the OSes package management system to still be used.

If not, will a dually P3 with a half-gig of RAM and a couple 7200RPM UW SCSI drives be enough of a machine to run my apache, php, etc daemons in User Mode Linux or under Xen without a hiccup?

Not planning on trying to get slashdotted or dugg anytime soon, and I can probably arrange to get mirrored in a couple of places if I see something like that coming.
