No problem, I'm in the same situtation.

Actually, I think there's three eggs here.

Syslog: The syslog functions.

Daemon: Mostly a clone of C's or Perl's daemon() function. Could be a wrapper to 
the C function.

Daemonize: A more robust daemonization function/library that can take care of 
PID files, output redirection to log files, and anything else related to 
managing a daemon. It may include functionality from Syslog, if appropriate (I'm 
not sure right now). It should probably be named something other than Daemonize, 
though.

The Syslog and Daemon eggs might be best off merged into the Posix unit.

Indeed, it may be appropriate to have different functions for daemonizing the 
current processing and forking a new daemon process.



Let me know what you think about merging daemon and syslog into posix, if you 
agree we should see what everyone else thinks and go from there.
