prepare(){
  cd "${pkgname}-v${pkgver}"
  ./autogen.sh
}

build(){
  cd "${pkgname}-v${pkgver}"
  ./configure --prefix=/usr     \
              --disable-doc     \
              --sysconfdir=/etc \
              --localstatedir=/var
  make
{

package(){
  cd "${pkgname}-v${pkgver}"
  make DESTDIR="${pkgdir}" install
  rm -rf "${pkgdir}/usr/lib/systemd/"
}

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-contrib-1.11.0-1-$(uname -m).pkg.tar.xz \
   /srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
         /srv/pacman/repos/LFS/pacman-contrib-1.11.0-1-$(uname -m).pkg.tar.xz

Update the local cache and install the Pacman-contrib package: 

pacman -Syu
pacman -S pacman-contrib --overwrite \* -dd --noconfirm

Finally, copy the source files into the source repository and clean up the build directory: 

mkdir /srv/pacman/source/LFS/pacman-contrib
cp PKGBUILD /srv/pacman/source/LFS/pacman-contrib
cd /sources
rm -rf pacman-contrib
