time/babysitting for upgrades and to enable or use new features or
functionality.
I worry far more about upgrades to proprietary appliances (where it's
often the whole system image), than I do about a few package updates on
a Linux machine (followed by a service restart, or two).
But still, pretty well worded. :)

Can't speak for other brands these days but F5s have two hard disks in
them. You can upgrade the software on the hot-spare, boot off that and
confirm everything is working. If it isn't you can just switch back.
