[gentoo-user] Emerge question: What's with the @?

[Chris Lieb]

I've noticed lately on the ML that people have been talking about using
package sets, such as @world and @installed.  I figured it was a part of
portage 2.1.6* since using @world with 2.1.4* would result in an error
message about an invalid package atom.  However, after upgrading to
portage 2.1.6.4, I still get the same error when doing something like
'emerge -up @world'.

What are these package sets?  What is the difference between 'emerge -up
world' and 'emerge -up @world'?  Why don't these package sets ever work
for me?

Thanks,
Chris

You can use sets since portage-2.2. There is no sets in 2.1 branch.

A set is basically just group of packages, you can either define you own
using /etc/portage/ or using gentoo provided ones like @world and @system
(which will replace the current emerge system/world usage eventually),
aswell as useful sets such as @live-rebuild (any package that uses a
cvs/svn/git eclass, so basically any -9999 ebuild) and @module-rebuild which
is handy for rebuilding kernel modules. Also id imagine meta-packages will
eventually move over to sets as it makes rebuilding everything or removing
it much easier, currently theres only kde4 that makes large usage of sets
but id imagine once portage 2.20 goes stable we'l see great set adoption.
An easy way to see what sets are available is to use the emerge --list-sets
command.

Thanks for the info.  The @module-rebuild should come in handy.  Any
idea on when we'll see 2.2* hit stable?

Thanks again,
Chris

Id imagine it will be a while yet, there are still a few problems with sets
and other new features that are being ironed out still, currently the only
way to get 2.2 is to unmask it.

The tracker bug for portage 2.2 problems is:

"When it's ready" I guess is the standard answer there. :) it's masked
in ~arch as well, but you can simply unmask it if you want to use it.
That's what I did. I have these sets available in my system currently:

    downgrade
    installed
    live-rebuild
    module-rebuild
    preserved-rebuild
    security
    system
    unavailable
    world

@live-rebuild is especially handy to rebuild live cvs/svn/etc ebuilds
(that -9999 stuff)

Same, here, ive been a happy user of portage 2.2 for a long time now and im
very happy with it and loving the ability to use sets. As with all programs
in ~ARCH (and especially as its also masked and under active development)
there may be occassional bug or other random error, but if your comfortable
working around them and/or reporting them then portage 2.2 is definately
worth a try :)
