Having grown up under Solaris, which was BSD-flavored at one time, and then added SysV commands, and when Linux was on the ascent, added the GNU suite ... all I have to say is, bring it! All the inconsistent compile options for sed, find, things that look the same but don't act the same. Bah! :) It mystified me that epel packages install by default in /opt so you have to stick /opt/rh/blah/bin in PATH, and the attendant libraries. Considering the OS war in the 90s between Microsoft and Sun, it's a little funny, like cry-a-bit funny. Mr. McNealy would be surprise how his spats (probably for show) with Mssrs. Gates and Ballmer turn out.
