Subject: [RFC/PATCH] Add hardening settings to uuidd.service
Date: Mon, 12 Nov 2018 22:10:31 +0100	[thread overview]
Message-ID: <20181112211031.21996-1-andreas@fatal.se> (raw)

This limits what the uuid daemon has access to when it runs.

Further improving this with additional option or making
things even tighter is most likely possible.
