[TriLUG] LVM2 on a new gentoo system

[Owen Berry]

Peter,

I'm using LVM (not LVM2) on Gentoo and set everything up at install
time. I fumbled my way through a combination of the standard
installation instructions and an LVM installation guide for Gentoo
(http://www.gentoo.org/doc/en/lvm.xml).

My /, /boot and swap partitions are not on LVM, to assist in recovery.
This was really useful to me as I stuffed things up at least once during
the install, but was able to recover and fix things using a LiveCD. I'm
sure it'll be useful at some stage down the road as well. The author of
the above document makes similar recommendations.
