the idea i thought might be doable, would be to allow multiple -d options to 
nagios, and allow those to be a file or a directory.

this would keep working:

[  ]# /usr/sbin/nagios -d /etc/nagios/nagios.cfg

and allow

[  ]# /usr/sbin/nagios -d /usr/share/nagios/conf.d/ -d /etc/nagios/conf.d/

to work too.

internally, instead of one file, we'll have to have an array of files/dirs, so 
that reloading nagios would also expand the config files/dirs into files and 
parse them all in order...
