efibootmgr 17-1ubuntu2 (amd64 binary) in ubuntu mantic

 This is a Linux user-space application to modify the Intel Extensible
 Firmware Interface (EFI) Boot Manager configuration. This application can
 create and destroy boot entries, change the boot order, change the next
 running boot option, and more.
 .
 Additional information about (U)EFI can be found at http://www.uefi.org/.
 .
 Note: efibootmgr requires that the kernel module efivars be loaded prior
 to use. 'modprobe efivars' should do the trick if it does not
 automatically load.
