No no. This is not the approach. You're WRITING THIS CODE YOURSELF
RATHER THAN USING A CPAN MODULE. I hope you have lots of tests for
this wheel...

BTW, I'd need a copy of Stevens handy to be sure, but I recall that
the canonical unix daemonisation dance goes:
double fork
close standard file descriptors
become session leader (POSIX::setsid IIRC)
become process group leader (POSIX::setpgrp IIRC)
set signal mask to ignore SIGHUP
change working dir to root
set file creation mask (umask)
drop privileges

I might well be missing a step. I think you did, too, though.
