Description Zac Medico gentoo-dev 2017-02-07 20:07:52 UTC
In some situations, it is permissible to break dependencies of installed packages. For example, consider a temporary/disposable container running in a continuous integration environment, where there is no thread of negative consequences. In situations like this, it's useful to have an option to disregard @world/@system/@selected, in order to avoid conflicts when solving dependencies for packages given as emerge arguments (possibly resulting in a serious system breakage).

    emerge: add --ignore-world [ y | n ] option (bug 608564)
    Ignore the @world package set and its dependencies. This may be useful
    if there is a desire to perform an action even though it might break
    the dependencies of some installed packages (it might also remove
    installed packages in order to solve blockers). This also alters the
    behavior of --complete-graph options so that only deep dependencies
    of packages given as arguments are included in the dependency graph.
    This option may be useful as an alternative to --nodeps in cases where
    it is desirable to account for dependencies of packages given as
