Does an upgrade BIN file actually upgrade the whole virtual appliance including the OS, or am I stuck with the old OS and only the software on it is upgraded?
IMHO the advantage of using a provided OS would be that I don't have to care about it but the manufacturer does. I however have the feeling that some manufacturers provide the virtual appliances with the argument that's it's much easier, but foremost to them, because it probably saves them support costs.
Which is true in this case? Can I be certain that the OS is safe and up-to-date? We are talking about a network management platform after all.
Can I run updates against the Ubuntu online repos without losing support? (Of course I won't dist-upgrade.)
