Comment 4 for bug 933843

The VCS repo module is hardish to move to, since we use a modified version of it that changes behaviour. It is possible that all the behavior we use is possible now in the latest puppetlabs-vcsrepo module. This should be investigated.

Do we use nginx anywhere? I've always seen apache everywhere.

The stdlib module should be as easy as upgrade it in install_modules.sh.

I have a review in flight that upgrades the apt module. This also means we can use the apt modules' unattended_upgrades functionality instead of our own rolled stuff. https://review.openstack.org/#/c/102739/

Mysql... I'm not sure. Will investigate.
