A report from pgCon 2013
Little things that matter in language design
works very well, no LVM needed.
I've also been bit my LVM and mount by UUID several times (did you know that mounting by UUID doesn't work if you have too many drives in your system? at least on some distros)
Fedora and LVM

That's fine for a fresh install. I believe the use case was for a easily revertable upgrade. Not the same thing.

- create an new filesystem with a different label on the unused partition
- copy the old system over
- change the label for the root filesystem in /etc/fstab to the new one (I would also grep through /etc/ for the old label eg. xubuntu1204, debian60, just in case)
- chroot into the new system and install grub to the new root partition and update-grub (or install and reconfigure extlinux... :)
- activate the new and deactivate the old partition
If anything goes wrong just reboot into the old root. Using "MBR" this is a simple matter of pressing the shift-key and choosing the right partition at boot time.

Setting up LVM (with snapshots for /) might be a bit more difficult during the initial install, but it seems to me it is going to be a lot more convenient in the end.
In either case, you have to have done something up front during the initial install. i.e. Either used LVM or set aside a partition for your second root.
