A few months ago, I've had to have a Red Hat Enterprise server built for a client.
This was my first "serious" experience with a Linux build other than Gentoo.
i had most of the "hard core setup" stuff done by more experienced techs and tried my hand at setting up a few simpler ones.
At first, I felt an intense frustration. I was used to the flexibility portage and yum was missing all these nifty switches to add the modules I was looking for.
However, the feeling of having a package installed in mere seconds (instead of the long time taken to rebuild everything) was refreshing.
