The question really comes down to how much new stuff do you want to learn?  Once you drink the LVM Kool-Aid you need to drink it hard since your filesystems are sitting on top of it.  My suggestion is keep a LVM HOWTO in hard copy next to your machine in case something blows up.

I just ran into that problem when trying to boot an older Knoppix disk I had lying around to try to recover a LVM2-enabled machine.   It kept insisting it was UNIONFS and did not seem to have a LVM2 module available at all.

Luckily, the Gentoo Install CD has the LVM2 modules so you can use the Gentoo install CD to troubleshoot any LVM-enabled disk.

But once you get the hang of using LVM2 it isn't THAT bad.   My suggestion is
stick with ext2 or ext3 filesystems if you want the true dynamic capabilities you can
get with LVM.   JFS and XFS as far as I know don't seem to support LVM.
