Comment 0 for bug 1506169

I just installed wily and am already getting:
Calculating upgrade... The following packages were automatically installed and are no longer required:
  linux-headers-generic linux-image-generic python-notify thermald
Use 'apt-get autoremove' to remove them.

I've done a few things to make it make my install my own, but I haven't been able to figure out what would have made these packages auto-removable.
