Just installed arch for the first time and in some ways loved it.
It has the minimalist feel of Gentoo but without the time taken to compile all of the source.
But still has a lot of the work in doing a stage 3 install al be it somewhat quicker.
Hmm do I prefer Gentoo or Arch or the ease of something like Ubuntu.
I hate all of the crap that is installed with a base install of Ubuntu but if you go with Ubuntu server you can trim it down loads.
Then again I Love Gentoo's Portage package management system, it is awesome!!!!
pacman is good but does not have le flexability of overlays.
Ubuntu provides for adding additional sources which are handled by the builtin package manager.
But with arch you have to have wrappers for pacman such as pacaur to install non-official packages which is'nt really intuitive.
In so many ways this could be a good thing, bringing a powerful linux system to the masses.
But in others a bad thing bringing a powerful tool with out knowing how to use it!
