If this is the first time you have run "updateall", you may need to be patient. The first time it is run, your computer is calculating all the dependencies between the different packages, and saving them in a local database. From there, all updates are managed by diff files against what's stored in the database, and other than the first time it's run, is almost always faster than any other package manager available.
There's no local cache updated on the first updateall. I suspect that what you saw was that the first time you ran it, you were competing with PackageKit updating its own cache, and after that, you didn't happen to conflict with PackageKit and so it ran faster.
Note that similar text shows up later in the conary overview, in "Updating via the command line"
Epiphany - GNOME Web Browser
Epiphany, http://www.gnome.org/projects/epiphany/, is the default web browser for GNOME and Foresight Linux.
Fortunately, this is no longer true! Yay!
sudo conary update group-gnome-devel
Would be better to say:
sudo conary update group-gnome-dist-devel
because that will keep your devel packages in sync because it contains both groups.
All Foresight documentation is created and maintained on the wiki.
Is that true for the user guide per se?
