the problem with atomicity is how to behave when it's an automatic run?

yum -y update

if package foo, bar and baz can't be updated b/c of some sort of
dependency behavior should I fail or should I just warn?

What if the command line was:
yum -y update foo bar baz

if foo and bar can't be updated should I just update baz or should I
look at the command line and see what the user asked for?

what if the command is yum -y update foo*

should I figure out all matches and see if it's reasonable to bail out?

All of the above is about describing expected behavior so the user is
not SHOCKED when something happens on their system that maybe they
didn't ask for.
