[Nottingham] Microkernal GNU Mach (with GNU Hurd)

[Alex Tibbles]

<snip>

AFAIK you can't simply plug a Hurd kernel in instead
of a linux kernel. See
http://web.walfield.org/papers/hurd-installation-guide/english/hurd-install-guide.html#SEC2
for details (sorry if it wrapped).

I can't remember the name but there was a
complete-sounding micorkernel for PowerPC (probably on
slashdot) a month or so ago. The author seemed to
claim that the cost of a context switch on Intel
hardware was so much higher than on, say, PowerPC,
that it wasn't worth porting. Does anyone know
sufficient in this area to say whether this is a
product of misinformation and lack of understanding?

It's meant to work with the GNU system so it does
support gcc et al.
