I often have more than one installation and each new installation includes an 
unchanged /srv partition and lists each previous installation as another 
available partition unchanged but under an amended name, so instead of / it 
may be /wheezyroot. I can then edit the previous /etc/fstab to match the new 
uuids and make all bootable. I also find the shared /srv partition useful.
