Warning: Updating to Ubuntu 13.10 deleted /var!

Maybe it was my situation, or how I went about the upgrade but on the same machine which had started out 12.04, then via 'do-release-upgrade' became 12.10 (which didn't delete /var), and then just this week via downloading ISO for 13.10 and using option for "Updating existing installation"-- wiped and replaced /var.

Be warned!

P.S. This was Ubuntu Gnome 13.10 dev 64-bit
