systemd First, fix a build error when using Util-Linux built in Chapter 5: sed -i "s:blkid/::" $(grep -rl "blkid/blkid.h") Disable two tests that always fail: sed -e 's@test/udev-test.pl @@' \ -e 's@test-copy$(EXEEXT) @@' \ -i Makefile.in Create a file to allow systemd to build when using Util-Linux built in Chapter 5, to disable LTO by default, and to build without xlstproc: cat > config.cache << "EOF" KILL=/bin/kill MOUNT_PATH=/bin/mount UMOUNT_PATH=/bin/umount HAVE_BLKID=1 BLKID_LIBS="-lblkid" BLKID_CFLAGS="-I/tools/include/blkid" HAVE_LIBMOUNT=1 MOUNT_LIBS="-lmount" MOUNT_CFLAGS="-I/tools/include/libmount" cc_cv_CFLAGS__flto=no SULOGIN="/sbin/sulogin" XSLTPROC="/usr/bin/xsltproc" EOF LTO is disabled by default because it causes systemd and other auxiliary programs to link to libgcc_s.so, slows the build down and makes the compiled code larger. Prepare systemd for compilation: ./configure --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --config-cache \ --with-rootprefix= \ --with-rootlibdir=/lib \ --enable-split-usr \ --disable-firstboot \ --disable-ldconfig \ --disable-sysusers \ --without-python \ --with-default-dnssec=no \ --docdir=/usr/share/doc/systemd-&systemd-version; --config-cache This switch tells the build system to use the config.cache file which was created earlier. --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. --without-python This switch prevents configure from trying to use Python which isn't built in LFS. --disable-firstboot This switch prevents installation of systemd services responsible for setting up the system for the first time. They are not useful for LFS because everything is done manually. --disable-ldconfig This switch prevents installation of a systemd unit that runs ldconfig at boot, making the boot time longer. Remove it if the described feature is desired, even though it's not useful for source distributions such as LFS. --disable-sysusers This switch prevents installation of systemd services responsible for setting up the /etc/group and /etc/passwd files. Both files were created early in this chapter. --with-default-dnssec=no This switch turns off the experimental DNSSEC suport. Compile the package: make LIBRARY_PATH=/tools/lib This package has a test suite, but it can only be run after the package has been installed. Install the package: make LD_LIBRARY_PATH=/tools/lib install Remove an unnecessary directory: rm -rfv /usr/lib/rpm Create the Sysvinit compatibility symlinks, so systemd is used as the default init system: for tool in runlevel reboot shutdown poweroff halt telinit; do ln -sfv ../bin/systemctl /sbin/${tool} done ln -sfv ../lib/systemd/systemd /sbin/init Create the /etc/machine-id file needed by systemd-journald: systemd-machine-id-setup Since the testsuite largely depends on the host system kernel configuration, some tests may fail. It also needs a modification in order not to look for a program that will be installed by Util-Linux package later in this chapter. To test the results, issue: sed -i "s:minix:ext4:g" src/test/test-path-util.c make LD_LIBRARY_PATH=/tools/lib -k check Installed programs Installed libraries Installed directories bootctl, busctl, coredumpctl, halt, hostnamectl, init, journalctl, kernel-install, localectl, loginctl, machinectl, networkctl, poweroff, reboot, runlevel, shutdown, systemctl, systemd-analyze, systemd-ask-password, systemd-cat, systemd-cgls, systemd-cgtop, systemd-delta, systemd-detect-virt, systemd-escape, systemd-hwdb, systemd-inhibit, systemd-machine-id-setup, systemd-mount, systemd-notify, systemd-nspawn, systemd-path, systemd-resolve, systemd-run, systemd-socket-activate, systemd-stdio-bridge, systemd-tmpfiles, systemd-tty-ask-password-agent, telinit, timedatectl, and udevadm libnss_myhostname.so.2, libnss_mymachines.so.2, libnss_resolve.so.2, libnss_systemd.so.2, libsystemd.so, libsystemd-shared-231.so, and libudev.so /etc/binfmt.d, /etc/init.d, /etc/kernel, /etc/modules-load.d, /etc/sysctl.d, /etc/systemd, /etc/tmpfiles.d, /etc/udev, /etc/xdg/systemd, /lib/systemd, /lib/udev, /usr/include/systemd, /usr/lib/binfmt.d, /usr/lib/kernel, /usr/lib/modules-load.d, /usr/lib/sysctl.d, /usr/lib/systemd, /usr/lib/tmpfiles.d, /usr/share/doc/systemd-&systemd-version;, /usr/share/factory, /usr/share/systemd, /var/lib/systemd, and /var/log/journal Short Descriptions bootctl used to query the firmware and boot manager settings bootctl busctl Used to introspect and monitor the D-Bus bus busctl coredumpctl Used to retrieve coredumps from the systemd Journal coredumpctl halt Normally invokes shutdown with the -h option, except when already in run-level 0, then it tells the kernel to halt the system;
