Late to the party, but +1 for OS-neutral names. Keep in mind, there's no separate update/upgrade steps on Windows. There's no "list of software that exists" that needs to get updated on Windows, as that is done automatically. Luckily, it sounds like we want update to always happen on Ubuntu anyway, so we don't need to find a name for it.
I suggest "install-updates" as the name for "apt-get upgrade" / "install windows updates" / whatever it is on CentOS. I think ugprade-system is too easy to confuse with "upgrade the OS to a new version".
