I know Debian has now KFreeBSD. Its installed on my PC currently however, the PC is working extremely glitchy and the DE which is Gnome 2 is forced on me. Any other OS option I choose like LXDE locks up. In addition, the Gnome 2 that's there doesn't work that well. It seems like using KFreeBSD I stepped into a time warp and went back to the days of Hardy Heron.
Would be great to see if someone could port Mint to BSD, removing all the linuxisms to do that and polishing it up. I know its a tall order but considering the NVIDIA driver is on BSD already, least there would be 3D support for people with NVIDIA cards.
I dunno maybe call the BSD version of Mint, MBSD standing for Mint BSD.
