Thanks for posting a patch that would serve as a good discussion
starter.  This is not a criticism on your patch, but more is a RFD
to those who helped our use of Travis by contributing to .travis.yml
and ci/.

Don't we need to do some other things so that we can run in vm
environment, rather than in container environment, before doing this
change?  IOW, aren't we doing in .travis.yml something we can do
only in container but not in vm (if there is any), and if so,
shouldn't we be rewriting that something so that we can run in vm?

I know ce59dffb ("travis-ci: explicity use container-based
infrastructure", 2016-01-26) only added "sudo: false" without doing
anything else (e.g. adding things that are only available to those
who run in container), but if we added stuff that are not usable in
vm environment after that commit since then, we need to adjust them
so that we can migrate to the container-based environment, no?

To me, removing that "sudo: false" line seems like the least thing
we need to worry about.  After all, they say that whether we have
"sudo: false" or not, the CI jobs will start running in vm
environment and not in container.  So if the rest of .travis.yml is
ready to run in vm environment, we do not have to do anything ;-).

In short, my question to Lars and SZEDER is, are we already prepared
to be thrown into a vm environment?

If the answer is "yes", then I think removing "sudo: false" is
probably still a good thing to do for documentation purposes
(i.e. showing that we knew we are ready to go through their
