Como remover o conjunto do portage

Question

Eu estava lidando com muitos blocos de Qt5.

  (dev-qt/qtchooser-0_p20150102:0/0::gentoo, ebuild scheduled for merge) pulled in by
    dev-qt/qtchooser required by (dev-qt/qtpositioning-5.4.0:5/5::gentoo, ebuild scheduled for merge)
    dev-qt/qtchooser required by (dev-qt/qtgraphicaleffects-5.4.0:5/5::gentoo, ebuild scheduled for merge)
    dev-qt/qtchooser required by (dev-qt/qtcore-5.4.0:5/5::gentoo, ebuild scheduled for merge)
  ...

Mas eu não tinha qt5 instalado (provavelmente removido um por um - eu estava tentando resolvê-lo há algum tempo):

# equery list qt*-5*
 * Searching for qt*-5* ...
!!! No installed packages matching 'qt*-5*'

Eu até adicionei -qt5 aos sinalizadores USE.

Eu lembro que usei alguns conjuntos qt5 via emerge --ask @qt5-essentials @qt5-addons e os conjuntos de listas confirmam isso.

# emerge --list-sets
...
qt5-addons
qt5-essentials
qt5-tools

mas eu não consigo encontrar nenhuma maneira como se livrar deles - não há opções de emergência. E o diretório de conjuntos personalizados não existe:

# ls /etc/portage/sets/
ls: cannot access /etc/portage/sets/: No such file or directory

    

Answer 1

AFAIK não há comando.

Verificando /var/lib/portage/world_sets revela a verdade:)

# cat  /var/lib/portage/world_sets
@qt5-addons
@qt5-essentials

Após a remoção, a atualização completa (@world) não se queixa mais.

Da próxima vez, verifique primeiro man emerge , os conjuntos são mencionados no início:

set    A set is a convenient shorthand for a large group of packages. Three sets are currently always available: selected, system and world. selected contains the user-selected  "world"  packages  that  are
       listed  in /var/lib/portage/world, and nested sets that may be listed in /var/lib/portage/world_sets. system refers to a set of packages deemed necessary for your system to run properly. world encom‐
       passes both the selected and system sets. [See FILES below for more information.] Other sets can exist depending on the current  configuration.  The  default  set  configuration  is  located  in  the
       /usr/share/portage/config/sets  directory.   User  sets  may  be  created  by placing files in the /etc/portage/sets/ directory (see portage(5)). Note that a set is generally used in conjunction with
       --update. When used as arguments to emerge sets have to be prefixed with @ to be recognized. Use the --list-sets action to display a list of available package sets.
