At first glance the library appears to close all open files, with an option
to exclude some specific file descriptors (that is, you need to pass a list
of files that shouldn't be closed). 

That makes it a lot harder to do some initialization before daemonizing.
I prefer to perform at least some initialization early in program startup to
be able to give sensible error messages. I've had too many initscripts that
claimed to have started a daemon sucessfully, only to have that daemon stop
right away because it noticed a problem right after it detached itself.
