I guess for now this is acceptable, because the snippet is similar to editing the conf file (as Sumit noted) but it would be nice to at least note in the design page of the fallback config and this merging feature that they are interconnected.. > Of course sssd will have an cli option to > use alternative directory for snippets (similar > to what we use for config file now). > Does anyone use the -c option actually (maybe except tests?) If not, do we need to add a new option?

Does libini provide that info? _______________________________________________ sssd-devel mailing list sssd-devel@lists.fedorahosted.org https://lists.fedorahosted.org/admin/lists/sssd-devel@lists.fedorahosted.org
