The keywords.conf (Gentoo and derived distributions) or platforms.conf (Exherbo) file
controls which keywords are and are not accepted. It is a standard configuration file which may be a bash file
(keywords.bash or platforms.bash) and which may use the keywords.conf.d/ or
platforms.conf.d/ directory.
Each line in the file consists of a specification followed by one or more accepted keywords or platforms. A specification may be any of:
*/*, which matches all packages. Nearly all users will have at least one
line using this specification.category/package name.set name.Any token may be quoted using either single or double quotes.
Accepted keywords pr platforms are one of:
keyword, which accepts any package containing that keyword.~keyword, which accepts any package containing that ~keyword. This does not automatically
accept the regular, non-tilde keyword.*, which accepts any package, including one with empty keywords or platforms.-*, which cancels any previously accepted match (see below).Accepted keywords or platforms are usually cumulative, so if you have a */* arch ~arch line, you will
need to use cat/pkg -* arch if you only wish to accept arch for a particular package.
For a system which is mostly stable:
# By default, only accept 'x86' packages */* x86 # For the repository named 'paludis-overlay', accept unstable too */*::paludis-overlay x86 ~x86 # For these packages, accept unstable too app-admin/eselect ~x86 app-doc/doxygen ~x86 # For packages in the 'kde' set, accept unstable kde ~x86 # Accept gcc 4.3 from the toolchain overlay, even if it is unkeyworded sys-devel/gcc:4.3::toolchain *
For a system which is mostly unstable:
# By default, accept stable and unstable */* amd64 ~amd64 # For these packages, accept stable only sys-devel/gcc -* amd64 sys-libs/glibc -* amd64
