Move from a base group to a base meta package

[lazka]

See https://lists.archlinux.org/pipermail/arch-dev-public/2019-January/029435.html and https://wiki.archlinux.org/index.php/Meta_package_and_package_group

By having a package we can easily add/remove packages from the base system.
For example we could split pacman and pacman-contrib (which atm get built together, but contrib builds against the previously installed one) without users losing pacman-contrib.

Open questions:

• What will win in case of pacman -S base if we have both a group and a package named "base"?

What will win in case of pacman -S base if we have both a group and a package named "base"?

I just checked with a dummy package and a dummy repo:

$ cat > PKGBUILD
pkgname=("base")
pkgver=1
pkgrel=1
pkgdesc="All your base are belong to us"
url="https://msys2.org/"
arch=('any')
license=('custom')
source=()
sha512sums=()

package() {
    touch "${pkgdir}/BASE"
}
^D

$ makepkg
[...]

$ repo-add test.db.tar.xz base-1-1-any.pkg.tar.xz
[...]

# echo "[test]" >> /etc/pacman.conf
# echo "Server = file://$(pwd)" >> /etc/pacman.conf
# pacman -Sy
[...]

# pacman -S base
