The BLFS Systemd Units package contains the systemd unit files that are used throughout the book.
Package Information
        The BLFS Systemd Units package will be used throughout the BLFS book
        for systemd unit files. Each systemd unit has a separate install
        target. It is recommended that you keep the package source directory
        around until completion of your BLFS system. When a systemd unit is
        requested from BLFS Systemd Units, simply change to the directory,
        and as the root user, execute the
        given make install-<systemd-unit>
        command. This command installs the systemd unit to its proper
        location (along with any auxiliary configuration scripts) and also
        enables it by default.

        It is advisable to peruse each systemd unit before installation to determine whether the installed files meet your needs.
