I am using ArchLinux for some weeks now, I have installed it on my IBM/Lenovo ThinkPad T60, and I must say I really like it, I will post here some few tips about it if you want to give it a try. We need to know that ArchLinux (Like Gentoo) is a rolling release, that means that there are no releases like in Debian or Ubuntu, where from time to time you get a new fresh release, and you have to upgrade it, in ArchLinux the packages are constantly being updated, so to have the last version or Arch once installed, just enter this two commands:
sudo pacman -Syy
This is to update the database, just like
sudo aptitude update
in Debian or Ubuntu.
Well later perform the update.
sudo pacman -Su
And that is all, you should run these commands, lets say once a week, and you will stay up to date.
