Error trying to add chrony as runit service

Hi everyone. arch/pacman/runit n00b here, but lots of Linux experience.

Pretty fresh install of Artix, just a lot of package adds so far, so I think I haven't messed anything up... yet.

Here's the error, by itself:
Code: [Select]
sv start chrony
fail: chrony: unable to change to service directory: file does not exist

I hope, some useful context:
Code: [Select]

install -d -m750 -o chrony -g chrony /run/chrony
exec chronyd -n -u chrony
Artybus-Max:[root]:~# ls -o /run/chrony/

But chrony runs OK standalone:
Code: [Select]
Artybus-Max:[root]:~# chronyd -dd -L -1
2025-01-18T19:45:39Z chronyd version 4.6.1 starting (+CMDMON +NTP +REFCLOCK +RTC +PRIVDROP +SCFILTER +SIGND +ASYNCDNS +NTS +SECHASH +IPV6 -DEBUG)

2025-01-18T19:45:44Z System clock TAI offset set to 37 seconds

And I thought maybe once it had run standalone, any needed directories would be created, but even after that:
Code: [Select]
Artybus-Max:[root]:~# sv start chrony
fail: chrony: unable to change to service directory: file does not exist

Here's the run script:
Code: [Select]
Artybus-Max:[root]:~# cat /etc/runit/sv/chrony/run
#!/bin/sh
install -d -m750 -o chrony -g chrony /run/chrony
exec chronyd -n -u chrony

I can run the "install" command in the shell, and it completes without errors. If I run the "exec chronyd...." the shell exits, and there's no chrony process created.

grepping /var/log/everything/current for "chrony" doesn't reveal anything useful.

I don't know what to check next. Any help appreciated.

probably your init script is not linked to svdir. read the wiki.

I think it is, unless I'm misunderstanding 'svdir'.

I did ln -s /etc/runit/sv/chrony /run/runit/chrony

Which matches the instructions in the wiki, if I'm reading it right.

By default services provided by Artix packages aren't in the svdir and can't be started or managed by any tool. To do so it is needed to link the service directories into the desired runlevel directory. For example, the following command allows to supervise a service in the current runlevel:

 ln -s /etc/runit/sv/service_name /run/runit/service

And, when I check /run/runit, the link for chrony is there.

I see where the confusion came from.
You need to link inside the "/run/runit/service" directory. so the link syntax would be:
Code: [Select]
 ln -s /etc/runit/sv/chrony /run/runit/service
