Problems upgrading to Ubuntu 15.10

1. A bad swap file entry in /etc/fstab stopped systemd from booting
2. systemd did’t like my ssd optimizations:
   • tmpfs /var/lock tmpfs defaults,noatime,mode=0755 0 0 # had to be commented out
   • had to do: mkdir /etc/tmpfiles.d/console-kit.conf to stop another error message
