Subject: [PATCH] resolv.conf.5: DESCRIPTION: Mention that the data is trusted.
Date: Tue, 18 Feb 2014 18:09:57 -0500	[thread overview]
Message-ID: <5303E845.7080003@redhat.com> (raw)

In a recent discussion about DNSSEC it was brought to my
attention that not all system administrators may understand
that the information in /etc/resolv.conf is fully trusted.
The resolver implementation in glibc treats /etc/resolv.conf
as a fully trusted source of DNS information and passes on
the AD-bit for DNSSEC as trusted.

Would it be possible to add a clarifying setence to the
man page for resolv.conf.5 to make it absolutely clear that
indeed this source of information is trusted?
