Not to make this a discussion of politics, but there's a saying about
democracy that applies here: It sucks... until you start looking at the
alternatives.

Interesting story, regrettably snipped for brevity.
FWIW, I learned bash from the bash appendix to Linux in a Nutshell... and
by then diving right in and rewriting some of the initscripts Mandrake
was shipping at the time (2002), so I got good experience right away on
how bash scripting is actually used in the field.
IMO, that's one of the bad things about doing away with shell-based
initscripts -- it's removing a VERY effective way to learn "practical
bash in field use"!
For years I referred back to that appendix when I had a question on some
minor detail. I went thru two editions of Linux in a Nutshell, that
way. Now I know much of it, but still refer to the manpage or builtin
command help occasionally.

Very good. And it's not a bother, for sure! It's a bit of a fun
challenge to see if I've mastered it enough to explain, etc! =:^)
