That's right, but if one begin from scratch with another language like C in
view,perhaps there are new ideas for designing a OS, new point of views to
the
problem how manage hardware resources quickly, safe, fault-tolerant (and
other things) to many processes, users, tasks ... Perhaps, from a new Ada
kernel
there come new impulses how Ada is good for, how it can be used as well.
I think, a interesting idea if not used to rebuild the Linux as Linux as it
is now
with the only difference in the language used.
