For those that like playing with arcane commands and systems; check out "Plan 9 from User Space"[0]. A port of Plan9's default applications that runs on Linux or MacOSX.
ACME[1], a text editor, is a great starting point.
A Unix-WINE for Plan 9, so we could run legacy Linux apps on a more modern OS.
And never forget: Plan 9 was just a stage and not the end of the developmental line. That was Inferno.
Plan 9 abstracts the network away into the filesystem.
Inferno does all that too and abstracts away CPU architectures as well, so the same compiled binary runs on x86 and ARM and RISC-V and whatever you happen to have.
Thanks for the info. I was aware of them, but a VM isn't what I meant.
WINE isn't a VM or an emulator: it "just" translates Win32 API calls to Linux ones. Getting that working has required implementing a load of DLLs and things, but it works surprisingly well now.
An environment to let Linux binaries launch on Plan 9 (or insert preferred derivative here: 9front, Harvey, Jehanne OS, whatever), akin to the Linuxulator in FreeBSD or the Linux Zone on Solaris, would make the OS much more usable.
I know what Wine does, for sure. Linuxemu and BSDemu did that, the same as Linux_compat on free/netbsd or Wine, but with vmx the former emulation it's obsolete.
