mon.* and osd.* sections are not
mandatory in config. So unless you want to set something per
daemon, you can skip them completely.

I use some self written ansible rules to deploy the config and crate the OSD with ceph-disk. Because ceph-disk use the next free OSD-ID, my ansible scrip is not aware which ID belongs to which OSD and host. So I don't create any [OSD.ID] section in my config and my cluster runs fine. Now I have read in [1] "the Ceph configuration file MUST specify the host for each daemon". As I consider each OSD as daemon, I'm a bit confused that it worked without the host specified. Why do the OSD daemon need the host option? What happened if it doesn't exist? Is there any best practice about naming the OSDs? Or a trick to avoid the [OSD.ID] for each daemon?
