21 No, that doesn't make sense. The situation you presented above was
22 removing "impossible to remove" components on an OS and asking if the
23 software still works. You don't get to call that a vaild test

32 Actually, business has a stock answer of "Supported on Windows XP or
33 later, Mac OS X some cat, Red Hat version foo, SuSE...."

35 In general they target actual known platforms, and YES they get to say
36 "I cannot support Centos 4 on this" all the time.

48 Hoo boy what I would give for -euDNtv to take less than 3 hours on my setup ;)
