Exhibit A: Package managers exist. Exhibit B: Autoconf exists. I rest my case.
no. install the latest copy of ubuntu. look for the autotools. not there? thats right. somehow debian/unbuntu and derived distros are capable of installing tens of thousands of packages without nary a compiler installed.
An operating system should have a simple, clear, consistent design. Not unlike a certain programming language named after a dead mathematition
unix is indeed largely consistent as originally conceived and executed through most of its history. simple small tools. everything is a file. ascii config files.
Still, I don't have the skill to write a functioning operating system
writing an operating system in haskell would solve absolutely nothing. in the end the userland is still a much larger portion of the codebase, or should we rewrite all of that too?
