The author built zmx as a learning exercise in Zig, POSIX, daemons, and terminals, and discovered the double-fork technique while researching daemon creation in abduco. The article explains the fundamentals of POSIX daemons, how fork() works, and the cascade of concepts behind the double-fork pattern for creating robust daemon processes.
