On Fedora 16, I used zif. zif is an alternative to yum and its fast!
How to setup zif? So easy: sudo yum install zif zif-tools
All set!
Search for packages using zif:
sudo zif search mongodb
Do a offline serach ( like cached -C in yum ):
sudo zif search -o mongodb
Install packages using zif:
sudo zif install mongodb-server mysql-server
Update all packages:
sudo zif update
And if you feel like canceling the operation using Ctrl+C, it happens almost instantaneously!
I like it.
