Remove that reference to avoid possible confusion: sed -i '/timesyncd.conf/d' src/timesync/timesyncd.conf.in Prepare systemd for compilation: Create a file to declare some variables cat > config.cache << "EOF" KILL="/bin/kill" MOUNT_PATH="/bin/mount" UMOUNT_PATH="/bin/umount" SULOGIN="/sbin/sulogin" XSLTPROC="/usr/bin/xsltproc" EOF ./configure \ --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --libexecdir=/usr/lib \ --docdir=/usr/share/doc/systemd-&systemd-version; \ --with-rootprefix="" \ --with-rootlibdir=/lib \ --enable-split-usr \ --disable-firstboot \ --disable-ldconfig \ --disable-lto \ --disable-sysusers \ --with-default-dnssec=no \ --with-kbd-loadkeys=/bin/loadkeys \ --with-kbd-setfont=/bin/setfont \ --with-dbuspolicydir=/etc/dbus-1/system.d \ --with-dbussessionservicedir=/usr/share/dbus-1/services \ --with-dbussystemservicedir=/usr/share/dbus-1/system-services \ --config-cache The meaning of the configure options: --config-cache Use the created config.cache. --with-root* These switches ensure that core programs and shared libraries are installed in the subdirectories of the root partition. --enable-split-usr This switch ensures that systemd will work on systems where /bin, /lib and /sbin directories are not symlinks to their /usr counterparts. --disable-firstboot This switch prevents installation of systemd services responsible for setting up the system for the first time. They are not useful for CLFS as everything is done manually. --disable-ldconfig This switch prevents installation of a systemd unit that runs ldconfig at boot, and increases boot time. While it may be not useful for source distributions like CLFS, this option may be removed. --disable-lto This prevents the build system from using GCC's Link-time optimization (LTO), to ensure that systemd's binaries will not try to link to libgcc_s --disable-sysusers This switch prevents install of systemd services which setup the previously created /etc/group and /etc/passwd files. --with-dbus* These switches ensure that D-Bus configuration files get installed to the correct locations. --with-default-dnssec=no This switch turns off the experimental DNNSEC support.
