how do i know i need a reboot after a console based "upgrade"?

[Mike.Kent at indystar.com]

Why would you do a dist-upgrade every day? Wouldn't that be likely to 
break things, such as apps that use an old version of php or perl?

That would be true, but you stated the converse - not that you will only
need to reboot on a "dist-upgrade", but that when you do "dist-upgrade" 
you
will (generally) need to reboot.

The latter entirely depends how often you do a dist-upgrade.  I do a
dist-upgrade _every day_.  I rarely need to reboot :-)
