>Description:
It seems that daemons installed into /usr/local/etc/rc.d require
a setsid() call in their startup code or they cannot be
auto-started using the /etc/rc.conf file.
This was the case with the printing daemon "ekpd" in /ports/print/pips730,
which I installed for my EPSON ink jet.
Although the daemon can be run fine manually, it would not start when
I placed the following in my /etc/rc.conf file:
> ekpd_enable="YES"
> ekpd_flags=""
Trace statements showed that the daemon was terminating at the end of
FreeBDD's startup, right before the login prompt appeared.
Kind Regards,
Jarrod.
>How-To-Repeat:
I would suggest that other daemons which do not call setsid() (or daemon())
after their fork() will also be killed of at the end of startup.
To verify this try installing /usr/ports/print/pips730 and adding the
above ekpd_enable line to your rc.conf. You should find that the daemon
is killed immediately before the login prompt appears after FreeBSD has
completed booting.
>Fix:
The following patch to the file:
/usr/ports/print/pips730/work/pips730-2.5.2/ekpd/cbtd.c
fixes the problem.
