Wes Felter, the proprietor of Hack The Planet, (who
really needs to get off the ETP bandwagon, IMO), points
our, quite rightly, that Novell can't have violated the GPL by
using XFree86 code since it isn't GPLed. Absent any deeper
investigation, Wes appears to be right about this.
It still raises an interesting issue: just how often is GPL
code distributed in proprietary, closed source products? My
guess is that it's more often than we might think.
Anyway, thanks, Wes, for pointing out what I should have
noticed.
