If you keep multiple installations on your system. Use a different volume group for system data (/, /usr, /opt, /var....) for each installation.
Then you can vary on each volume group as needed and mount the LVs wherever you need.
As for dual booting it, you either disable distro automatic updating of grub's menu.lst or equivalent, and stick images and initrds in the same one with different parameters for each. Or you setup a /boot partition for each installation and have grub chainloading grub.
Or you could just stop wasting time dual booting. If you like hand holding managing virtual machines there exists virtual box and vmware. If you're more of the DYI type, kvm, kqemu, and xen work well enough.
