Re: [DNG] Felker Init: was without-systemd.org not working
Citando Steve Litt : This whole discussion balances on the definition of "shell aware". What is "shell aware?" SteveT Have you tried to write shell script code into the execution command of a systemd unit file? it doesn't work right?! Why do you think it doesn't work? For it to work you need 2 files, ... the service unit , and also a shell script, But SysVInit only needs a script, no service unit required.. so its more optimized, only a file to control something.. Why in hell would you need to create several files to control the same thing? Its stupid.. Now in relation to s6, I need yet to read about it, maybe there are improvements.. Does s6 do the same mistake as systemd, with having 2 files for the same thing? The Linux Stadard Base, have defines the LSB Headers, as a way to control the services.. And their definition was in the same file as the daemon is.. So we expect only 1 file.. ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

I mean, of course, testable in the real world. Meanwhile, a skeptical observer would note at least two serious problems with your ad-hoc conspiracy hypothesis: (1) Over a decade, exactly zero departed Red Hat employees have spilled the beans on such an alleged conspiracy. (Threatening ex-employees with litigation over violating their employment confidentiality agreements doesn't actually work very well, especially given robust means of publishing corporate details without personal attribution.) (2) You didn't bother to tell a credible story about RHAT revenue, etc., i.e., how your alleged conspiracy makes non-fantasy business sense. RHAT/IBM's business model has been an open book since August 1999, when RHAT went public. Since then, it's been pretty obvious why they did what they did. When I shave the post-2010 Poettering history using Occam's Razor, I find that the parsimonious answer to why they adopted in RHEL and CentOS his system glue to be super-obvious: It's partly about their move into container-oriented cloud computing, e.g., his systemd code's utility as a cgroups manager. Among other things, IBM/RHAT famously haven't given a tinker's damn about 'Linux desktop computing' since the late 1990s, by contrast. > Conspiracies happen.

I'm curious whether such a legal action would get dismissed _first_ for lack of standing, or for failure to state a cause of action.

Let's not confuse a theory that something is caused by several people, acting together, with people spouting fact-averse, science-hostile, logically incorrect kiddiebabble. Now here's a fact.

Oh please don't suggest this: Poettering might do it. The job of an init system (not systemd, that's a software analogy of those old electronic circuits encased in epoxy so nobody could reverse engineer them) is to: 1) Run as PID1, listening for certain 2) PID1 forks off early boot stuff to mount, unencrypt, construct devices, set up the network, and the like. 3) PID1 forks off a daemon handler. The best daemon handlers are, in my opinion, djb style process supervisors like daemontools, runit and s6. 4) Upon receipt of a certain signal, PID1 forks or execs the shutdown script. It really is just that simple. There's no need to add anything to accommodate badly behaved init system authors.
