# NOTE: You must run `pacman-key --init` before first using pacman; the local

# packagers with `pacman-key --populate archlinux`.
#
# REPOSITORIES
# - can be defined here or included from another file
# - pacman will search repositories in the order defined here
# - local/custom mirrors can be added here or in separate files
# - repositories listed first will take precedence when packages
# have identical names, regardless of version number
# - URLs will have $repo replaced by the name of the current repo
# - URLs will have $arch replaced by the name of the architecture
#
# Repository entries are of the format:
# [repo-name]
# Server = ServerName
# Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
#
# An example of a disabled remote package repository with multiple servers
# available. To enable, uncomment the following lines. You can add preferred
# servers immediately after the header and they will be used before the
# default mirrors.

#SigLevel = Required
#Server = ftp://ftp.example.com/foobar/$repo/os/$arch/
# The file referenced here should contain a list of 'Server = ' lines.

As was done with the GlibC package, we are creating files in the
source array on the fly, so we'll need to update the MD5 Sums:
updpkgsums
Prepare the build directory for the pacman user and build the
package:
chown -R root:pacman .
chmod 2775 .
chmod 664 PKGBUILD
su pacman -c 'makepkg -L --nodeps'
Add the newly created package to the central package repository:
cp pacman-7.0.0-1-$(uname -m).pkg.tar.xz \
/srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
/srv/pacman/repos/LFS/pacman-7.0.0-1-$(uname -m).pkg.tar.xz
Update the local cache and install the Pacman package:
pacman -Syu
pacman -S pacman --overwrite \* -dd --noconfirm
Finally, copy the source files into the source repository and clean
up the build directory:
mkdir /srv/pacman/source/LFS/pacman
cp PKGBUILD /srv/pacman/source/LFS/pacman
cd /sources
rm -rf pacman
