Nice set of links as always, Aaron.  Thanks.

Insta-assessments:  The FHS link is very barebones on this subject, but at
least has a sentence or two about the intended role of all top-level
directories including /proc and /sys.  The Stackexchange link is an
ideal starting point, concise, short, and spot-on.  The Quora link gives
a bit more surrounding detail and also has the advantage of brevity.

First Youtube link is a somewhat meandering 10-minute tour elementary
through /proc and /sys.  Second is similar and shorter, with a slightly
different emphasis including use of sysctl (good!).  Both are not bad if
being shown stuff video-style helps one learn.


Something I mentioned briefly at this evening's BALUG meeting:  My
friend Bodo Bauer back when he was working at the now-vanished SUSE
Linux office in Oakland (in 1999, I'm pretty sure) published online in
HTML format two key chapters of an intended book, detailing very
usefully almost all features of /proc in the then-prevalent Linux
kernels.  I still have it here:

Bodo and a co-author went on to make that part of a larger 600 page
technical book for IDG Books, _Suse Linux Internals_, mentioned here:
https://www.amazon.com/SuSE-Linux-Internals-CDROM-Bauer/dp/0764545957
https://books.google.com/books/about/Suse_Linux_Internals.html?id=EecUkgEACAAJ

Of course, all contents being last millennium makes them less useful
now, but I suspect it's solely a matter of (lesser) scope of coverage
rather than [in]accuracy.  (And yes, 1999-2000 is indeed a long time
ago.)
