Related, whomever is specifying quay.io needs to specify 'quay.io.',
with the trailing dot. The trailing dot signifies a Fully Qualified
Domain Name (FQDN). The trailing dot means the dns name starts at the
top of the DNS tree, and search domains won't (should not?) be added.
Or maybe I should say, won't be added in a proper functioning
implementation.
