This may be used to temporarily exclude + directories from aging by taking the same lock (useful for example + when extracting a tarball into /tmp or /var/tmp as a privileged user, + which might create files with really old timestamps, which + nevertheless should not be deleted). For further details, see: + + https://systemd.io/TEMPORARY_DIRECTORIES + + * systemd-tmpfiles' h line type gained support for the + FS_PROJINHERIT_FL ('P') file attribute (introduced in kernel 4.5), + controlling project quota inheritance. + + * sd-boot and bootctl now implement support for an Extended Boot Loader + (XBOOTLDR) partition, that is intended to be mounted to /boot, in + addition to the ESP partition mounted to /efi or /boot/efi. + Configuration file fragments, kernels, initrds and other EFI images + to boot will be loaded from both the ESP and XBOOTLDR partitions. + The XBOOTLDR partition was previously described by the Boot Loader + Specification, but implementation was missing in sd-boot.

In this setup, the underlying root device is not + modified, and any changes are lost at reboot. + + * Similar, systemd-nspawn can now boot containers with a volatile + overlayfs root with the new --volatile=overlay switch. + + * systemd-nspawn can now consume OCI runtime bundles using a new + --oci-bundle= option. This implementation is fully usable, with most + features in the specification implemented, but since this a lot of + new code and functionality, this feature should most likely not + be used in production yet. + + * systemd-nspawn now supports various options described by the OCI + runtime specification on the command-line and in .nspawn files: + --inaccessible=/Inaccessible= may be used to mask parts of the file + system tree, --console=/--pipe may be used to configure how standard + input, output, and error are set up. + + * busctl learned the `emit` verb to generate D-Bus signals. + + * systemd-analyze cat-config may be used to gather and display + configuration spread over multiple files, for example system and user + presets, tmpfiles.d, sysusers.d, udev rules, etc. + + * systemd-analyze calendar now takes an optional new parameter + --iterations= which may be used to show a maximum number of iterations + the specified expression will elapse next. + + * The sd-bus C API gained support for naming method parameters in the + introspection data. + + * systemd-logind gained D-Bus APIs to specify the "reboot parameter" + the reboot() system call expects. + + * journalctl learnt a new --cursor-file= option that points to a file + from which a cursor should be loaded in the beginning and to which + the updated cursor should be stored at the end. + + * ACRN hypervisor and Windows Subsystem for Linux (WSL) are now + detected by systemd-detect-virt (and may also be used in + ConditionVirtualization=). + + * The behaviour of systemd-logind may now be modified with environment + variables $SYSTEMD_REBOOT_TO_FIRMWARE_SETUP, + $SYSTEMD_REBOOT_TO_BOOT_LOADER_MENU, and + $SYSTEMD_REBOOT_TO_BOOT_LOADER_ENTRY. They cause logind to either + skip the relevant operation completely (when set to false), or to + create a flag file in /run/systemd (when set to true), instead of + actually commencing the real operation when requested. The presence + of /run/systemd/reboot-to-firmware-setup, + /run/systemd/reboot-to-boot-loader-menu, and + /run/systemd/reboot-to-boot-loader-entry, may be used by alternative + boot loader implementations to replace some steps logind performs + during reboot with their own operations. + + * systemctl can be used to request a reboot into the boot loader menu + or a specific boot loader entry with the new --boot-load-menu= and + --boot-loader-entry= options to a reboot command. (This requires a + boot loader that supports this, for example sd-boot.) + + * kernel-install will no longer unconditionally create the output + directory (e.g. /efi//) for boot loader + snippets, but will do only if the machine-specific parent directory + (i.e. /efi//) already exists. bootctl has been modified + to create this parent directory during sd-boot installation. + + This makes it easier to use kernel-install with plugins which support + a different layout of the bootloader partitions (for example grub2). + + * During package installation (with `ninja install`), we would create + symlinks for systemd-networkd.service, systemd-networkd.socket, + systemd-resolved.service, remote-cryptsetup.target, remote-fs.target, + systemd-networkd-wait-online.service, and systemd-timesyncd.service + in /etc, as if `systemctl enable` was called for those units, to make + the system usable immediately after installation.
