Unfortunately for Linux-based systems this will be always a usability

Having gcc pre-installed and ready to use is a good thing but somehow I
always thought that "apt-get install gcc" on Debian(s) fulfill the need.
FYI, Solaris 10 shipped with gcc pre-installed too but for different
reasons obviously, like compiling FOSS, etc. OpenSolaris drivers are
written using kernel DDI interface which is not changing as often as
unstable Linux kernel interfaces. Usually driver compiled years ago
should work just fine on any OpenSolaris based distro such as NexentaOS.
So, theoretically, the best way to resolve a Linux kernel driver problem
would be to convince Linus to stabilize kernel interfaces at some point.
But for now, shipping gcc pre-installed + kernel headers and wrappers to
re-build drivers on the fly like DKMS is the best option. Its ugly and
creates a lot of headaches for an end users especially with a new
hardware which is not "main-line" accepted yet. But it seems to be a
right way to go for Ubuntu for now.
