17:07 < infinity> hallyn: Well, that certainly shouldn't change the permissions on the underlying dir, as that's immutable.
17:07 < infinity> hallyn: But copying up, changing permissions, and using that copy would seem sane.

Title:
  Filesystem mount from lxc template causes filesystem permission
  breakages

Status in juju-core:
  Triaged
Status in lxc containers:
  Confirmed
Status in “linux” package in Ubuntu:
  Confirmed
Status in “postgresql” package in Juju Charms Collection:

Bug description:
  In juju-core 1.17.5, creating new lxc machines is now much faster as
  it appears to be using a template machine. In addition, the root
  filesystem is mounted from the template machine.

  Unfortunately, this causes filesystem permissions to screw up.

  juju deploy ubuntu
  juju ssh ubuntu/0
  sudo chown ubuntu:ubuntu /etc/ssl/private
  ls /etc/ssl/private

  That final 'ls' fails with a permission denied. This is possibly a
  security precaution in lxc or the filesystem.

  This issue breaks the postgresql charm. The PostgreSQL packages
  require and use the ssl-cert package, which changes /etc/ssl/private
  to be group readable by the ssl-cert group. The postgres user, a
  member of the ssl-cert group, is unable to read the private key stored
  in this directory.
