Subject: [ptxdist] Patch: Allow installation of /etc/hosts as a link to /run/hosts
Date: Tue, 6 May 2014 19:30:28 +0200 [thread overview]
Message-ID: <CABDcavZ_W8hvdTtw=Q_KvK3OS=hq3jktHhmWjdyrm5yAujFg3w@mail.gmail.com> (raw)
Hi all,
Here's a patch that allows installation of /etc/hosts as a link to
/run/hosts
This is useful when the root filesystem is mounted read only.
A similar option already exists for /etc/resolv.conf
