Public bug reported:
My xenial gate jobs began failing after the nodes began running
4.4.0-159.
The gist of this bug is that a file sitting in /posix.ini for example,
copied there by ucf from /usr/share/php7.2-common/common/posix.ini,
cannot be read by non-root users despite its permission bits being 0644.
chmodding 0644 on top of the file fixes this, also rebooting the lxc
container solves it as well.
After downgrading the same test node to 4.4.0-157 and re-running the
same tests, the broken behavior does not occur.
Please see the attachments for the exact commands used to reproduce
this.
