Given that Trusty was released almost 4 years ago, is there any plans for getting a newer platform for grid users? This is partially in relation to T183090, there are some areas where the k8s just fail. What prospects are there for moving to a newer grid exec nodes? I would start to expect that we will be seeing more and more cases of software incompatibility or security issues arise as time passes, and that given the glacial speed at which such a move would take I am surprised we have not seen the first stages of a migration already in progress.
