Mistery about efibootmgr

Hi all,
using efibootmgr I see there are many different types of EFI boot entry (don't care about GUID):

Boot002B* UEFI OS    HD(2,GPT,a3...08,0x12c02f00,0x61b03e8e)/File(\EFI\BOOT\BOOTX64.EFI)0000424f
Boot0031* ubuntu    HD(2,GPT,c4...6c,0xe1800,0x32000)/File(\EFI\UBUNTU\SHIMX64.EFI)0000424f

If I create my own entry I see something like:

Boot0001* ArcoLinux    HD(1,GPT,68...1c,0x1000,0x96000)/File(\EFI\ARCOLINUX\GRUBX64.EFI)

... without numbers at the end... some entries has a longer sequence than this (not posted) at the end of.

It seems grub-install and Windows install program can create this kind of "numbered" entries.

My question is... what are the numbers at the end --->>> 0000424f  <<<<---  ?
Why efibootmgr cant create this entries with numbers ?

Methinks you need the -u switch.   Try efibootmgr -u

Edit:  Oh, Welcome to the Arch Linux forums.

Are you using ArcoLinux or Arch Linux?
