Loader Specification are read from /EFI/Linux/ on the ESP.
+
+ EFI Variables
+
+ The following EFI variables are defined, set and read by systemd-boot, under the vendor
+ UUID 4a67b082-0a4c-41cf-b6c7-440b29bb8c4, for communication between the OS and the boot
+ loader:
+
+
+
+ LoaderBootCountPath
+ If boot counting is enabled, contains the path to the file in whose name the boot counters are
+ encoded. Set by the boot
+ loader. systemd-bless-boot.service8
+ uses this information to mark a boot as successful as determined by the successful activation of the
+ boot-complete.target target unit.
+
+
+
+ LoaderConfigTimeout
+ The menu time-out. Read by the boot loader. (Also, modified by it when the
+ t/T keys are used, see above.)
+
+
+
+ LoaderDevicePartUUID
+
+ Contains the partition UUID of the EFI System Partition the boot loader was run from. Set by
+ the boot
+ loader. systemd-gpt-auto-generator8
+ uses this information to automatically find the disk booted from, in order to discover various other partitions
+ on the same disk automatically.
+
+
+
+ LoaderEntries
+
+ A list of the identifiers of all discovered boot loader entries. Set by the boot
+ loader.
+
+
+
+ LoaderEntryDefault
+ LoaderEntryOneShot
+
+ The identifier of the default boot loader entry. Set primarily by the OS and read by the boot
+ loader. LoaderEntryOneShot sets the default entry for the next boot only, while
+ LoaderEntryDefault sets it persistently for all future
+ boots. bootctl1's
+ and commands make use of these variables. The boot
+ loader modifies LoaderEntryDefault on request, when the d key is used, see
+ above.)
+
+
+
+ LoaderEntrySelected
+
+ The identifier of the boot loader entry currently being booted. Set by the boot
+ loader.
+
+
+
+ LoaderFirmwareInfo
+ LoaderFirmwareType
+
+ Brief firmware information. Set by the boot loader. Use
+ bootctl1 to view this
+ data.
+
+
+
+ LoaderImageIdentifier
+
+ The path of executable of the boot loader used for the current boot, relative to the EFI System
+ Partition's root directory. Set by the boot loader. Use
+ bootctl1 to view this
+ data.
+
+
+
+ LoaderInfo
+
+ Brief information about the boot loader. Set by the boot loader. Use
+ bootctl1 to view this
+ data.
+
+
+
+ LoaderTimeExecUSec
+ LoaderTimeInitUSec
+ LoaderTimeMenuUsec
+
+ Information about the time spent in various parts of the boot loader. Set by the boot
+ loader. Use systemd-analyze1
+ to view this data. These variables are defined by the Boot Loader
+ Interface.
