Hello Chris,

no problem I can provide you with a minimalist daemon replacement :)

Here is a simple perl minid script:
>cat minid.pl
#!/usr/bin/perl -w
# detach from tty
main:
$pid = fork;
exit if $pid;
die "fork: $!" unless defined $pid;
print "continue in child";
sleep(4000);

This is then the daemon "executable" minid.pl.


The changes in the init script are:


DAEMON="/path/to/your/minid.pl"

PARA=" "
. /lib/lsb/init-functions

With this you should be able to reproduce the behaviour.

Attached is the output of "-x" , it looks that the "pidfile"
or not giving a pidfile is the problem here.
Tested it on SuSE 10.1, works fine, but sometime reports
a stat error on proc, but works nonetheless (Suse, not debian)

regards,

Martin
