Quoting Peter Ross (petrosssit@gmail.com):
The beauty (and longevity) of Unix is its modular approach with clearly defined APIs.
Efforts to have this discussion tend to be doomed in advance because people mean various things when they use the word 'modular' (no kidding). See: http://uselessd.darknedgy.net/ProSystemdAntiSystemd/ It's good to review that page before launching arguments on this matter. But, that having been said, your point is an excellent one. If I need to replace my MTA with a different implementation, my sshd with a different one, my command shell with a different one, my choice of awk, my choice of grep, my choice of window manager, my choice of httpd, my choice of ftpd, I can do so without limitation because of clean, well-defined, modest, non-tangled programming interfaces that face towards other code. Poetteringware has over the years shown an increasing tendency to ignore and eschew that virtue, and systemd does so with a vengeance. And I, for one, intend to laugh heartily whenever I hear that there's a problem with some systemd module that cannot be avoided by switching to a compatible replacement because none exist. -- Cheers, "I don't need to test my programs.
