Starting xinetd in Void Linux.

Starting xinetd in Void Linux.

[peter]

Hi,

Void Linux has package xinetd for x86_64. Installed here with 
"xbps-install xinetd" in updated Void.

ls -l /etc/sv/xinetd/* 
-rwxr-xr-x 1 root root 47 Jan 14  2021 /etc/sv/xinetd/run
lrwxrwxrwx 1 root root 27 Jan 14  2021 /etc/sv/xinetd/supervise -> /run/runit/supervise.xinetd

The last line above flashes reverse video on a red background; a hint 
that /run/runit/supervise.xinetd doesn't exist. So xinetd failed to 
start.

I've read https://docs.voidlinux.org/config/services/.  No mention of 
/run/<anything>.

How does runit start a service?

Where in the process is /run/runit/supervise.<service> created?

A fix for this failure?

Thanks,                          ... P.

The Void Linux documentation could be better.

Did you follow the instructions in section "Enabling Services", and if something unexpected happened, what was that?

Once the service has been enabled, did you follow the instructions starting with "To start, stop, restart or get the status of a service", and if something unexpected happened, what was that?

It would be nice if their documentation provided a through-line example of installing a package, enabling a corresponding service, testing the service, and configuring the service to start on boot.  If you want them to do that, you might ask them at https://github.com/void-linux/void-docs.  Their documentation also says this about contributing: "If you have any questions, feel free to ask them via IRC in #voidlinux on irc.libera.chat, or in the voidlinux subreddit."

...yet. Correct tho.

No, not because of that. See below.

/run/<anything> is an implementation detail not worthy of being
mentioned. :)

The interesting part is
https://docs.voidlinux.org/config/services/#enabling-services
ln -s /etc/sv/<service> /var/service/

> How does runit start a service?

runsvdir will (within 5s) notice that /var/service/xinetd/ has appeared,
and then start "runsv xinetd".

runsv will notice that ./xinetd/supervise is a dangling symlink, and
create the directory (assuming /run/runit/ exists).

The only failure appears to be that you didn't enable the service before
expecting it to work.
Otherwise, what's the output of "sudo sv start xinetd"?

cheers,
