We have lots of configuration settings and it would be nice to have a centralized description (which we already have in a way in lib/config/config_settings.h) from which we could automatically generate the lvm.conf (including the comments) and lvm.conf man page entries so everything is always in sync and documented properly.
This could be an lvm dumpconfig extension. It would be very much like the existing "lvm dumpconfig --type default" we already have, but it would also include the extra (long) commentaries we have in the default lvm.conf at the moment, including examples etc.
(This is low prio, but if there's some spare time to look at this in more detail it shouldn't be hard to add this functionality).
