*YAAAAWWWWN*
Err, I mean....um....yay....and stuff.....I guess.
Seriously though, why would I use this? If I've got Linux then MariaDB and PostgreSQL are both just one command away and there's really not anything MS SQL does that's a big enough difference to justify dropping money on a license, let alone the extra aggravation of installing a product not endorsed by my disto of choice.
