freebsd stable - Mar 2004 - Linux emulation, rc.d and SIGHUP

Hi!

I've Linux multithreading daemon running under FreeBSD 4.9-STABLE
(cvsup'd today). Being started in multiuser, it goes backgroup and runs OK.
Being started at boot time from rc.d script, it starts and quickly
shuts down.

ktrace(1) show that it receives SIGHUP in the latter case.
Is it a bug in the Linux emulation? If not, how can I avoid this SIGHUP?

 No, native applications (for example, shell scripts) will also receive SIGHUP
at the end of boot process if they don't daemonize themself (note that going
to background != daemon(3)). Fortunately, we have daemon(8) utility now. So
I've replaced '/etc/ppp/start &' with 'daemon
/etc/ppp/start' everywhere to
get rid of this annoying SIGHUPs.

Sincerely, Dmitry
