One concern I have about this patch is that it replaces references to /var/run and /var/lock with /run and /run/lock, but the only explanation that /run should be used in place of /var/run is in a non-normative footnote. So we've effectively lifted the prohibition on shipping files under /var/run with this change, which isn't really what we want. Should it be spelled out in the normative bits of policy that packages "should" use /run for anything that the FHS says should be in /var/run, and that packages must not ship files under any of /run, /var/run, or /var/lock? -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
