I’m not too familiar with Debian as an OS, but as far as the installation process is concerned, its great. I’ve installed it onto a few machines now, and after a few installations its a breeze. The majority of installation is self explanatory, although there are a few steps I was unsure of. The first question being exactly what an LVM is used for and whether or not you should use a mirror. Aside from a few uncertainties I was able to get Debian up and running quickly and painlessly.
