many thx chris for the links. i was surprised to read this: "one of the
reasons for basing the CDDL on the Mozilla license was that the Mozilla
license is GPL-incompatible."
http://en.wikipedia.org/wiki/Common_Development_and_Distribution_License
looking further i saw: "The Free Software Foundation (FSF) considers the
license a free software license, albeit one with a weak
copyleft. However, "unlike the X11 license" (MIT License) the license
has "some complex restrictions" making it incompatible with the GNU
GPL. They urge people not to use the license because of this
incompatibility unless the provision in section 13 of the MPL is
exercised to provide the work under either the GPL or any other
GPL-compatible license.[2]
For these reasons, the Mozilla Suite and Firefox have been relicensed
under multiple licenses, including the MPL, GPL and LGPL."
http://en.wikipedia.org/wiki/Mozilla_Public_License#Compatibility_with_GPL
so that might be why firefox is called iceweasel on debian and nakamoura
on arch.
also, thx for the tips regarding my usb idea. i agree it isn't a good
one for several reasons. we'll stick to regular hard drives for now when
we switch from freebsd to debian in june.
