Idea for yum

[Peter Backlund <peter backlund home se>]

Hi.

I was fooling around with bash-completion, and noticed that the 
fedora.us package is already configured to complete yum commands and 
even package names. Unfortunately does "yum list" takes _really_ long, 
making package name completion unusable. But if you add

/usr/bin/yum -R 120 -e 0 -d 0 -C list | cut -d" " -f1 > 
/var/cache/yum/pkg-name-list

to /etc/cron.daily/yum.cron, and then modify /etc/bash_completion like:

install)
  COMPREPLY=( $( compgen -W '$( cat /var/cache/yum/pkg-name-list )' -- 
$cur ) )

in _yum(), you get a daily caching of the package names, and completion 
is instant. Very handy.

Also, would it be a good idea to make yum run with -C by default when 
"yum update" was run less than X seconds ago, where X is configurable? 
That would make sense if the cronjob service is used, since "yum update" 
is run once a day.
