efibootmgr on linux doesn't work

[Yann Diorcet]

On linux, if I try to change the efi boot order with the command efibootmgr, it doesn't taken in account:

Code: Select all

root@me-x86-64-0001c036581f:~# efibootmgr
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0000,0001
Boot0000* system0
Boot0001* system1
root@me-x86-64-0001c036581f:~# efibootmgr -o 1,0
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0001,0000
Boot0000* system0
Boot0001* system1
root@me-x86-64-0001c036581f:~# efibootmgr
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0001,0000
Boot0000* system0
Boot0001* system1
root@me-x86-64-0001c036581f:~# sync
root@me-x86-64-0001c036581f:~# reboot

After reboot

Code: Select all

root@me-x86-64-0001c036581f:~# efibootmgr
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0000,0001
Boot0000* system0
Boot0001* system1
