A meta package and a package group can be defined by the packager to denote a set of related packages. Both can allow to install or uninstall this set of packages simultaneously by using the meta package or the group name as a substitute for each individual package name. While a group is not a package, it can be installed in a similar fashion to a package, see pacman#Installing package groups and PKGBUILD#groups.

## Difference between meta package and package group

The difference between a meta package and a regular package is that a meta package is empty and exists purely to link related packages together via dependencies. A meta package, often (though not always) titled with the "-meta" suffix, provides similar functionality to a package group in that it enables multiple related packages to be installed or uninstalled simultaneously.

Each solution has advantages and disadvantages:

meta package:

- Meta packages can be installed just like any other package (see pacman#Installing specific packages).
- Meta packages can be removed like any other package (see pacman#Removing packages).
- Any new member packages will be installed when the meta package itself is updated with a new set of dependencies.
- Users cannot choose which meta package dependencies they wish to install.
- Users cannot remove meta package dependencies without having to uninstall the meta package itself.

group:

- Package groups will prompt users to select the packages from the group that they wish to install (see pacman#Installing package groups).
- Users cannot uninstall a group, because they installed a list of packages. Instead, `pacman -R groupname` tries to remove all members of the group.
- New group members will not be automatically installed.
- Users can choose which group members they wish to install.
- Users can uninstall group members without having to remove the entire group.

## Meta packages

The most important meta package is base. It contains a minimal package set that defines a basic Arch Linux installation. It includes:

- basics such as glibc and bash,
- distribution related things such as pacman and systemd
- POSIX tools such as core utilities, process, file and file compression utilities
- networking tools such as iproute2

The kernel is an optional dependency. See the announcement when it was introduced, and reasoning why base is a meta package.

## Groups

The most important package group is base-devel. It contains tools required to build many packages like GCC and make. See also makepkg#Usage.
