Re: "there are much more suitable options for that"
I remember that well!
Pragmatism vs purity.
I might still have my Minix somewhere. Nice learning tool. It predated Linux, I believe. (I used Minix on an 8086 back in ca '87.)
I'd argue that being for a micro kernel architecture is being knowledgeable, but being against other more pragmatic solutions as a consequence of that is less so.
Thanks for the link to that nostalgic look back at a flame war! Linus was just as undiplomatic then as now, so no news there!
