According my experience the most difficult OS to Install are Alpine (No GUI anywere), FreeBSD, NetBSD, OpenBSD (*BSD because use a different partition system and installer), as a matter of fact all personalization applied by the link was done after install.

This is so crazy for me. I don’t think all those articles take up much physical space, the FSF isn’t bankrupt. Why did they do it? destroy RMS’s legacy?

I didn’t note before :)
