The general population considers update synonymous with upgrade as has
been proven by millions of similar questions, comments, and assorted
waste of bandwith over the years. There can of course be nothing wrong
with popular usage of language because it, solely and it the first
place, is what using people make of it and do with it. The real problem
as usual was born when devs picked a theoretically correct but
practically unwise name for what they call an upgrade. That, should have
been named something else in the beginning, like uplevel or something
(remember IBM Warp's 'backlevel'?). Mind you, in such a case some would
still confuse uplevel with update :-)
As for the OP's question I think Yast's manual updating feature is
UNBEATABLE, after all Linux mortals should be able to use a keyboard but
only when they so desire. I update when I feel like it and I for one
would have liked to see Yast just as operational in Tumbleweed (don't
wanna get into why that could not work arguments).
