We should be listing all of the ones we define in the manual, if we aren't we
need to fix the manual. There isn't really a way to list them in the code
(other than searching it with "git grep") because the features are only really
defined by the checks that are made for them e.g.
${@base_contains('DISTRO_FEATURES', 'systemd', 'true', 'false', d)}
You are of course free to define your own DISTRO_FEATURES simply by checking
for them in your recipes (where it makes sense; typically PACKAGECONFIG is
used for configuration options for individual recipes these days and
DISTRO_FEATURES is left for features that are controlled system-wide).
Cheers,
Paul
