@mmu_man @dvl @jpmens Yeah, it looks like (though I cannot confirm tonight, need to actually compare tmux upstream with this repo to see the differences to be sure) that the only real dependency on Linux is for the namespaced jail; the implementers just didn't able or willing to port that logic for other OSes even though the build system and upstream tmux clearly supports them.
