Summary: start-stop-daemon with --make-pidfile and --pidfile
on httpd applet creates the wrong pid# in pidfile
Description:
When start-stop-daemon is starting the httpd applet, and told to make a
pidfile, it does so, but creates a pidfile containing the pid of the
original process not the running one. httpd probably starts and forks,
letting the parent die. There should be an option to httpd to prevent this
so you can use pidfiles for it created by start-stop-daemon.

This is also the case when using start-stop-daemon to start telnetd. So I
guess it applies to all servers that fork immediately and detach. I needed
the pid for httpd, and now need it for telnetd.
There is a work around in some cases. You can use start-stop-daemon to
send signals, like SIGHUP to servers, removing the need for pidfiles
generally.

Auto-daemonizing programs fork children, then parent dies. ssd have no way
detecting this.
Most of daemons have an option to suppress daemonization:
# telnetd --help
-F Stay in foreground
-i Run as inetd subservice
# httpd --help
-f Do not daemonize
Use this if you start them from ssd.
