Transporting a portable system: Unix to an IBM minicomputer (1983) [pdf]
Yeah the fact that Unix&#x2F;POSIX was once considered a minimal, easily ported OS is somehow lost in today&#x27;s Linux-centric world with Linux-only concepts such as namespaces, systemd, etc. It&#x27;s also strange that Docker has gained momentum when all it does is present a very shallow wrapper around Linux core APIs, thanks to Linux&#x27; excellent userspace compat.
