Use the proper syntax:

event_dispatchers=database
event_dispatchers=http

I know it sucks, it's oslo.config :(

[ZTE-Zhengwei Su (su-zhengwei)]

Your suggestion works, but is not perfect.

It can't config multi-key configuration by "openstack-config". There may be problem with packstack or devstack when install or update openstack. So I strongly recommend to modify the code.

What do you think?

[Julien Danjou (jdanjou)]

It's not a suggestion, it's the way it works.

If it's not supported by openstack-config, then you should fix openstack-config.

ListOpt and MultiStrOpt are real problem though in oslo.config and I think they should be unified; if you want to work on that in oslo.config, that'd be welcome too!
