That’s cool! The issue is that when you’re selling to a massive legacy institution, the infosec on a new Linux distro that self updates to new patches is really no bueno. We lost many months on this piece and on key deals. I heard from the grapevine that they ended up having to port DCOS to Ubuntu after all, soon after I left.
Yeah we disabled the auto updates and orchestrated the updates ourselves. Saved our bacon multiple times when kernel/systemd/docker bugs got pushed out.
