Then you should really ask yourself why they take that position. AFAICS, there is no solid technical argument for it.
I believe they just don't think about anything other than the main and so do the least possible rather than taking the extra steps (or have too much to think about or on the todo list already). Take firefox it has a compilation option of no dbus but if dbus fails it refuses to even start (dbus being a possible route to escape chroot). I had sorted that by just closing off the dbus after start-up but since upgrading now get a general "DBUS error" message. It was said the linux user space package dependency issue was getting better but I think it's relapsed and perhaps far worse or more lazy in some cases.
Now udev has been merged with systemd, and one can wonder why. According to the authors, it is 'because they share some common code'. A rather weak argument, that would be true for almost any two subsystems you can imagine.
This is a misrepresentation. Udev and systemd were merged I think mainly because they "belong together", but also because they had cyclic build dependencies as they are very tightly integrated.
It's no misrepresantation, but an almost literal quote from one of the authors.
Yes, systemd and udev are supposed to work closely together, that makes perfect sense. The solution preferred by grown-up programmers in such cases is to define stable interfaces on both sides allowing them to do that, not to merge them.
I've been wondering lately whether there is a good reason why even udev violates the "one thing and do it well" principle set forth by the co worker of the designer of C and Unix as it not only dynamically creates devices like mdev does but also hotplugging like hotplugd on OpenBSD. Hopefully there is a config option or you would need an alternative if you want static dev files and hotplugging. -- _______________________________________________________________________ 'Write programs that do one thing and do it well.
