systemd-efi-boot-generator — Generator for automatically mounting the
    EFI System Partition used by the current boot to
    /boot
/usr/lib/systemd/system-generators/systemd-efi-boot-generator
systemd-efi-boot-generator is a
    generator that automatically creates mount and automount units for
    the EFI System Partition (ESP), mounting it to
    /boot. Note that this generator will execute
    no operation on non-EFI systems, on systems where the boot loader
    does not communicate the used ESP to the OS, on systems where
    /boot is an explicitly configured mount (for
    example, listed in
    fstab(5))
    or where the /boot mount point is non-empty.
    Since this generator creates an automount unit, the mount will
    only be activated on-demand, when accessed.
systemd-efi-boot-generator implements
    the generator
    specification.
