we are now in the infrastructure freeze leading up to the Fedora 28
release. This is a final release freeze.
We do this to ensure that our infrastructure is stable and ready to
release the Fedora 28 when it's available.
You can see a list of hosts that do not freeze by checking out the
ansible repo and running the freezelist script:
ansible/scripts/freezelist -i inventory
Any hosts listed as freezes is frozen until 2018-05-01 (or later if
release slips). Frozen hosts should have no changes made to them without
a sign-off on the change from at least 2 sysadmin-main or rel-eng
members, along with (in most cases) a patch of the exact change to be
made to this list.
