[Bug 1761997] [NEW] /var/run needs mode 777 in bionic

[Mark Shuttleworth]

Public bug reported:

I saw some odd behaviour of screen during the upgrade from Xenial to
Bionic using do-release-upgrade. I was trying to use screen to reattach
to an upgrade process that had gone sideways during a router daemon
upgrade (duh). But I was told that the permissions on /run/screen needed
to be 777. Does the bionic version of screen have that as a requirement?
And if so, perhaps do-release-upgrade should set those permissions in
anticipation of the upgrade process so that screen works with both old
and new versions.
