-u implies --oneshot now, as does -N.
This is not reasonable! When is this readable in the man page?
(In reply to comment #1) > -u implies --oneshot now, as does -N. --update and --onlydeps are actually the only ones that imply --oneshot. The reasoning for --update implying it is that the user just want's to upgrade something rather than add it to the world file. You can always use emerge --noreplace to explicitly add an atom to the world file.
ok, now I use 'emerge -NnDva'
Thinking about it, I'm not sure if --update really should imply --oneshot. When it's overloaded like that, you can't get the "pure" --update behavior without --oneshot. In the 'emerge -NuDva nfs-utils' case, the --deep option overrides any effect that --update would have had, since nfs-utils isn't slotted (greedy atoms don't matter) and --newuse already implies --noreplace.
Another option would be to deprecate the --update option and split it into separate options. It's behavior that isn't currently available via other options could be represented with --greedy and --depth=n options where --greedy makes atoms greedy with respect to slots and --depth=1 would cause dependencies to be traversed to the same level that --update currently does.
(In reply to comment #6) > Another option would be to deprecate the --update option and split it into > separate options. I agree with the comment above that the old behaviour should be retained in some format. Why not just revert --update to old behaviour, and add the two new options? (I liked the --slots one as well tho ;)
Somebody was just complaining about this in #gentoo-portage so I've reverted --update so that it doesn't imply --oneshot anymore.
This has been released in 2.1.3.10.
