There are many more packages to fix, this is just a start.
Rules:
* Don't repeat the package name (not always that easy...)
* Start with capital letter
* Don't end with full stop
* Don't start with "The ..." or "A ..."
I've also added descriptions to some packages and rewritten others.
The source has HOSTNAME=`hostname` (capture output of hostname command)
but currently it is replaced with HOSTNAME="/path/to/hostname" (which is
just a plain string). Fix it by substituting with
HOSTNAME=`/path/to/hostname`.
