I recommend daemontools for Unices.

I can only second that. Writing daemons to be compatible with daemontools (i.e. forget about almost all aspects of running as a daemon) automatically makes them compatible with tons of other tools that copied the daemontools idea (almost all alternatives to a classic init, xinetd, and even the nightmare systemd).

See also:

Just another little note: If you write your daemon to be compatible with daemontools, it can be incredible compact. A hello world deamon can be written as a bourne shell script in less than 10 lines of code:

#!/bin/sh
# blabbyd.sh: a blabby daemon, version 2
#
# note: variables now provided from environment with envdir:
#
#   .env/MESSAGE
#   .env/PAUSE
#
echo "starting blabbyd..."
# loop forever
while :
do
    echo "blabbyd: ${MESSAGE}"
    echo "blabbyd: sleeping for ${PAUSE} seconds..."
    sleep ${PAUSE}
done
# that's all, folks!

(Copied right out of the djb way)

All that you think is missing for a daemon is already implemented by daemontools or some other, compatible software. You don't have to reinvent the wheel.
