If it had the drivers I needed I would run it. As Andy Tanenbaum
(ast@cs.vu.nl) author of MINIX said in early 1992 - LINUX is obsolete. 
It is a monolithic kernel you have to reboot every time you change a small
part of it, say to correct a DOS in the tcp/ip stack.

Tanenbaum goes on to moan about how unportabile Linux is ;-)

Hang on I just spotted another quote I must include:

If he had left out the SPARC bit he would have been about right.

If you go to http://www.gnu.org/hurd/ there are some more reasons why Hurd is
better than Linux.

On another thought why not run both? Yes that is right Hurd is actually
Hurd/Mach because it uses the Mach microkernel and Hurd is all the unix like
daemons on top. We could make that Hurd/Linux by striping Linux down to a bare

Think of the choice Debian GNU/Linux, GNU/FreeBSD, GNU/NetBSD, GNU/Hurd/Mach
GNU/Hurd/Linux, GNU/Hurd/FreeBSD, GNU/Hurd/NetBSD. And if we can get them all
to have similar system calls and run elf then the binaries will be compaitable
for systems with the same chip. You could install Debian GNU/Linux and then
change your mind and do apt-get install hurd-mach or apt-get install freebsd
and Debian will changes its kernel in front of your eyes. (apt-get install
win32 ????)

GNU does not eliminate all the world's problems, only some of them.
