Added a few more mappings for ~nyden and ran postmap.
Ran apt-get update and then apg-get install to add imagemagick at the request of a user.
I made a modification to the virtual file to include the domain nyden.us such that all mail to that domain (and a few specific addresses therein) all go to user Bill Nyden, ~nyden, on clone.
Then ran postmap on the file.
