[Bug 285742] usr.sbin/daemon refuses to shut down even after child is terminated

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285742

            Bug ID: 285742
           Summary: usr.sbin/daemon refuses to shut down even after child
                    is terminated
           Product: Base System
           Version: 14.2-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: dch@freebsd.org

14.2-RELEASE jail
tested with both /usr/sbin/daemon from 14.2-RELEASE & 
also 14-STABLE as of 20250329 unpacked from tar and dropped on top.

from 14-STABLE SHA256 (/usr/sbin/daemon) =
899300a90660afbb0340110b8f2244499cb32b0d52791e61c41a79ffedbb52b2

rc script from https://reviews.freebsd.org/D49563 is supposed to start &
stop both the supervised child & the parent via `service anubis stop`.

I've tried all 4 combos:

-r -P -p 
-r -P
-r -p
-r

And in each case the daemon does not die. Stubborn daemon! In some
cases the child is correctly terminated, but as daemon is still running
its not possible to start the service without `pkill -9 -ilf daemon`
or similar.

This should be at least an errata, as it impacts many many daemons in ports in
14.2-RELEASE,
and ideally would get fixed in the next patch release.
