Subject: [PATCH] allow secrets to be group-readable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Systemd's LoadCredential feature makes have the following 0o440 permissions.
Services cannot modify secrets or their permission.
By relaxing the check we allow buildbot to use secrets provided by systemd.
