Q: Which "package management" tool(s) did you install and

A: Fink. Although it doesn't work yet with macOS 11, so I may
have to change.
It's installed in /opt/sw
I'm guessing Fink and other tools that use /opt will get what
they want using
/etc/synthetic.conf, which is apple's workaround to making /
read-only.
I'm guessing they'll use the 'special link' approach, and put
their actual data
in either /usr/local/opt or /System/Volumes/Data/opt (again,
just a guess!).
I would hope they choose the former, as the latter is something
Apple could
change in future releases (as they often do with stuff they
just make up).
/etc/synthetic.conf tells the OS on boot to create empty dirs
and/or special kinds of
symbolic links to another place. This is apparently is Apple's
workaround to making
root completely unwriteable. With this approach, apparently
Apple can supervise
(and deny) what can be done in the root dir.
I had to make use of synthetic.conf to keep intact my NFS
mounting scheme that
I use across platforms, and refuse to change, which is
/net/<volnames>, so I
created a single line in the file:
/net /some/where/else
..which lets me put my actual mounts in /some/where/else.
Note that's a /tab/ between /net and /some/where/else; I
believe this is to allow
for spaces in the names (yuck) without having to use quoting.
