systemd First, apply a patch to fix the build with GCC-10: patch -Np1 -i ../systemd-&systemd-version;-gcc_10-fixes-1.patch Create a symlink to work around missing xsltproc: ln -sf /bin/true /usr/bin/xsltproc Set up the man pages: tar -xf ../systemd-man-pages-&systemd-version;.tar.xz Remove tests that cannot be built in chroot: sed '179,$ d' -i src/resolve/meson.build Remove an unneeded group, render, from the default udev rules: sed -i 's/GROUP="render", //' rules.d/50-udev-default.rules.in Prepare systemd for compilation: mkdir -p build cd build LANG=en_US.UTF-8 \ meson --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ -Dblkid=true \ -Dbuildtype=release \ -Ddefault-dnssec=no \ -Dfirstboot=false \ -Dinstall-tests=false \ -Dkmod-path=/bin/kmod \ -Dldconfig=false \ -Dmount-path=/bin/mount \ -Drootprefix= \ -Drootlibdir=/lib \ -Dsplit-usr=true \ -Dsulogin-path=/sbin/sulogin \ -Dsysusers=false \ -Dumount-path=/bin/umount \ -Db_lto=false \ -Drpmmacrosdir=no \ -Dhomed=false \ -Duserdb=false \ -Dman=true \ .. -D*-path=* These switches provide location of binaries needed by systemd at runtime that have not yet been installed. -Ddefault-dnssec=no This switch turns off the experimental DNSSEC support. -Dfirstboot=false 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. -Dinstall-tests=false This switch prevents installation of the compiled tests. -Dldconfig=false This switch prevents installation of a systemd unit that runs ldconfig at boot, which is not useful for source distributions such as LFS and makes the boot time longer. Remove it if the described feature is desired. -Droot* These switches ensure that core programs and shared libraries are installed in the subdirectories of the root partition. -Dsplit-usr=true This switch ensures that systemd will work on systems where /bin, /lib and /sbin directories are not symlinks to their /usr counterparts. -Dsysusers=false This switch prevents installation of systemd services responsible for setting up the /etc/group and /etc/passwd files. Both files were created earlier in this chapter. -Drpmmacrosdir=no This switch disables installation of RPM Macros for use with systemd because LFS does not support RPM. -D{userdb,homed}=false Remove two daemons that have dependencies that do not fit the scope of LFS. Compile the package: LANG=en_US.UTF-8 ninja Install the package: LANG=en_US.UTF-8 ninja install Remove an unnecessary symbolic link: rm -f /usr/bin/xsltproc Create the /etc/machine-id file needed by systemd-journald: systemd-machine-id-setup Setup the basic target structure: systemctl preset-all Disable a service that is known to cause problems with systems that use a network configuration other than what is provided by systemd-networkd: systemctl disable systemd-time-wait-sync.service Prevent systemd from resetting the maximum PID value which causes some problems with packages and units in BLFS: rm -f /usr/lib/sysctl.d/50-pid-max.conf Installed programs Installed libraries Installed directories bootctl, busctl, coredumpctl, halt (symlink to systemctl), hostnamectl, init, journalctl, kernel-install, localectl, loginctl, machinectl, networkctl, portablectl, poweroff (symlink to systemctl), reboot (symlink to systemctl), resolvconf (symlink to resolvectl), resolvectl, runlevel (symlink to systemctl), shutdown (symlink to systemctl), systemctl, systemd-analyze, systemd-ask-password, systemd-cat, systemd-cgls, systemd-cgtop, systemd-delta, systemd-detect-virt, systemd-escape, systemd-hwdb, systemd-id128, systemd-inhibit, systemd-machine-id-setup, systemd-mount, systemd-notify, systemd-nspawn, systemd-path, systemd-repart, systemd-resolve (symlink to resolvectl), systemd-run, systemd-socket-activate, systemd-stdio-bridge, systemd-tmpfiles, systemd-tty-ask-password-agent, systemd-umount (symlink to systemd-mount), telinit (symlink to systemctl), timedatectl, and udevadm libnss_myhostname.so.2, libnss_mymachines.so.2, libnss_resolve.so.2, libnss_systemd.so.2, libsystemd.so, libsystemd-shared-&systemd-version;.so (in /lib/systemd), 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;
