Subject: [PATCH v2] Allow systemd to getattr configfile
Date: Mon, 13 Jan 2020 18:27:11 +0000 [thread overview]
Message-ID: <20200113182658.3502291-1-dsugar@tresys.com> (raw)
v2 update - rework, creating interface 'init_systemd_conditional'
as suggested. This grants getattr access to the type provided.
