sv shutdown fails, even while sv stop works #27
Description
The "sv shutdown" command does not work as expected, even while the "sv stop" command does. See the screenshot below:
Not only does the "sv shutdown" command return an error, but the service is still running. Note that the service was apparently stopped and then restarted (the process ID of the /usr/local/bin/houseportal application is different).
The "sv exit" command behaves in the same odd way, which is not surprising since the man page indicates that shutdown is based on exit..
I just downloaded, installed (and updated, as per the installation manual) void-live-x86_64-20230628-base.iso.

Even weirder, if the service is stopped, then using "sv exit" restarts it. See screenshot:

The
runsvprogram is what supervises a service. It can be spawned directly or throughrunsvdir, which spawns and supervisesrunsvprocesses for all services found in the service directory.When using
sv <stop|down>, the correspondingrunsvprocess receives the signal to end the service it supervises, updates the status of the service, and continue listening for further signals (these are documented in therunsvmanual page).The
svcommand only ever send control signals to individual runsv processes. When the signal requires that therunsvprocess itself terminates, it does so. However, if it was started byrunsvdir, it will be automatically restarted, which will restart the service if its default state is notdown.
