GNU Mach is not fundamentally obsolete or bad, I really do not
understand where people get this idea from.
That's what is said about GNU Mach...
According to what Marcos told me, GNU Mach is fundamentally incapable
of properly doing the job we had in mind for it to do. This does not mean
it is fundamentally useless for all uses. It might be fine on a computer
only used by one person, according to my memories of the issues.
But that won't really excite people, I think. So we need Hurd-NG
for a real success.
