If it didn't we wouldn't have this thread.  Instead we would have one on "why 
is portage rebuilding all these packages?". It's just portage keeping us 
informed. It also lets us make decisions on which rebuilds we can skip until 
more convenient.

I suspect this ground has been covered in depth
but finding a good discussion of what it means is a different story.
So, is this bad news?  Or something that needs my attention...?


It doesn't seem to be anything but noise : why does Portage list them ?




It's the kind of thing you'd want to get with -v and not get without it

It doesn't seem to be anything but noise : why does Portage list them ?

You used to have to run revdep-rebuild to find packages that needed to
be rebuilt after an update. Portage got smarter, and now some of those
rebuilds can be triggered automatically.

It's perfectly normal and expected. The underlying mechanism is subslot
dependencies:
