For comparison: ~/.config/service-bundles/services/ and
~/.config/service-bundles/targets/

Tip: In the daemontools world all services have ther own service
directory, at minimum; and this directory is the working directory of
the service. You can put an mpd.conf that is particular to the service
in the service directory itself.

Note: This can be easily handled on FreeBSD and TrueOS. See NOTE_TRACK
in EVFILT_PROC for kevent().

One of the interesting developments over the past couple of decades is
how much the world has been influenced to come around to the daemontools
way of doing this. I've observed before, elsewhere, the number of
daemon programs, especially in the BSD worlds, that have in that time
gained -F/--foreground or similar options that tell them not to do a
whole bunch of this unnecessary stuff.

It's in a way somewhat saddening to see the new option to emacs that
started this thread. It's welcome; but the sad part is that it's a
decade and a half behind quite a lot of others. For some systems like
emacs the process has been glacially slow. MySQL is another.
daemontools users were asking about letting daemontools do the service
management and doing away with mysqld_safe in 2002. It took thirteen
years for it to happen ... in MariaDB. Oracle, where software goes to
die, may or may not have done the same for MySQL. PostgreSQL lags
further behind.
