Not quite. The UNIX wars were basically "Hardware" wars. Basically, you bought your workstation from Sun, or HP, or SGI, or IBM or whoever, and you got the version of UNIX that was shipped for that hardware. You could compile your own BSD (/usr/ucb) or GNU (/usr/local) utils if you didn't want to pay a king's ransom for a compiler, but basically, the idea of running any type of software on any hardware, a la Linux or OpenBSD, hadn't really caught on.

I know it's cool to be all blase about this, but this is different.
