Be careful not to confuse the advertisement about "microkernels"---I
mean the lie about the name proper---and the reality.
Plan9 was made by the fathers of Unix at a time when to be published
and acclaimed, one had to work on "microkernel". And the Plan9
paper has some ironical words about that. Because Plan9 is not a
"microkernel(TM)" but happens to be "micro" (minimal), efficient,
and for a totally distributed system. Things that "microkernels"
are unable to be at least for the 3 together. "Micro"kernels are
big; and since the efficiency is desastrous for distributed systems,
to "demonstrate" that they are the correct way they go backward to
assembly i.e. loose portability. Is Minix distributed in the same
sense as Plan9? Or is it Unix (not distributed)?
