[clug] systemd and systemctl poweroff

[George at Clug]

Hi,


Has anyone been testing Debian 10 (Buster)?


I went to "shutdown" and this did not work.


 I am guessing that due to systemd, shutdown has been removed?


So is now " systemctl poweroff" the preferred method?


The question I ask, "how is the a better solution?"  (maybe someone
can tell me).


I like the original Unix philosophy of "many small programs for each
task, not one monolithic program trying to do everything"


https://en.wikipedia.org/wiki/Unix_philosophy
The Unix philosophy, originated by Ken Thompson [1], is a set of
cultural norms and philosophical approaches to minimalist [2], modular
[3] software development [4]




The UNIX philosophy is documented by Doug McIlroy [5][1] [6] in the
Bell System Technical Journal from 1978:[2] [7] 



	* Make each program do one thing well. To do a new job, build afresh
rather than complicate old programs by adding new "features".
	* Expect the output of every program to become the input to another,
as yet unknown, program. Don't clutter output with extraneous
information. Avoid stringently columnar or binary input formats. Don't
insist on interactive input.
	* Design and build software, even operating systems, to be tried
early, ideally within weeks. Don't hesitate to throw away the clumsy
parts and rebuild them.
	* Use tools in preference to unskilled help to lighten a programming
task, even if you have to detour to build the tools and expect to
throw some of them out after you've finished using them.

It will be the end of Linux...
