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 migration).

As far as I understand, the container-based infrastructure has only one benefit over the VMs, the shorter startup time. OTOH, in VMs we can use sudo, which is not available in the container-based intra. This has the benefit that after switching to VMs, we'll be able to install packages by running 'sudo apt-get install ...'. Currently the necessary packages are listed in '.travis.yml' for Travis CI, while for Azure the whole install command is embedded in '.azure....yml'. After the switch we could consolidate installing packages by 'sudo apt-get...' in 'ci/install-dependencies.sh' for both. > 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.

I think we are. I've run only two builds with this patch, and they run smoothly and finished successfully. After you update 'pu' I'll run more. > 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 > migration).

Although I see I could have made this a bit clearer in the initial message. Having a patch that may cause a broken build or other CI problems seems more appropriate than waiting for Travis CI to flip the switch and searching for the problem afterwards. > 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?

Travis CI will soon deprecate the container-based infrastructure enabled by `sudo: false` in ce59dffb34190e780be2fa9f449f842cadee9753.
