which Daemonize package is recommended to use?

[Eugene Perederey]

I found at least three of those on hackage: hdaemonize
(System.Posix.Daemonize), direct-daemonize (System.Daemonize) and
System.Daemon from MissingH.
The latter one has 'provisional' stability, nothing is said about
stability of the other two.
Is there a standardized wrapper detaching a process from terminals or
shall I better do it myself?

[David Terei]

First one looks good to me. Second one don't touch.
