Bug ID: 282694
Summary: utility `daemon(8)` never exits (process SIGTERM) if
child process restarts indefinitely
Product: Base System
Version: 14.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me

basic minimal rc.d script for illustration purposes
Hi there,
attachment `testd.sh` minimal rc.d script that starts `daemon` for `env` which
always exits (just to illustrate), `-r` restarts `env` but `daemon` doesn't
reacts to SIGTERM in that mode which is the signal sent on `service testd
stop`, so it's hanging on waiting for PID indefinite:
```
~# service testd onestop
Stopping testd.
Waiting for PIDS: 19035^C
```
think there is a race condition for when `daemon` receives SIGTERM but in a
state when there is no child yet
