+
+ * The systemd-boot boot loader has been updated to optionally maintain
+ a random seed file in the EFI System Partition (ESP). During the boot
+ phase, this random seed is read and updated with a new seed
+ crytographically derived from it. Another derived seed is passed to
+ the OS. The latter seed is then credited to the kernel's entropy pool
+ very early during userspace initialization (from PID 1). This allows
+ systems to boot up with a fully initialized kernel entropy pool from
+ earliest boot on, and thus entirely removes all entropy pool
+ initialization delays from systems using systemd-boot. Special care
+ is taken to ensure different seeds are derived on system images
+ replicated to multiple systems.
+
+ * bootctl gained a new verb "is-installed" that checks whether
+ systemd-boot is currently installed.
+
+ * A new document has been added describing systemd's use and support
+ for the kernel's entropy pool subsystem:

– Somewhere, SOME-TI-ME
Features:
+* beef up s2h to implement a battery watch loop: instead of entering
+ hibernation unconditionally after coming back from resume make a decision
+ based on the battery load level: if battery level is above a specific
+ threshold, go to suspend again, only hibernate if below it. This means we'd
+ stick to suspend usually, but fall back to hibernation only when battery runs
+ empty (well, subject to our sampling interval). Related to this, check if we
+ can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
+ i.e. see if it can wake up machines from suspend, so that we could resume
+ automatically when the system is low on power and move automatically to
+ hibernation mode. (see
+ https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
+ section 10.2.2.8 and
+ https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
+ at the end).
+
* add an explicit "vertical" mode to format-table, so that "systemctl
status"-like outputs (i.e. with a series of field names left and values
right) become genuine first class citizens, and we gain automatic, sane JSON
* transient units:
- add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
-* Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
-
* when we detect low battery and no AC on boot, show pretty splash and refuse boot
* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
