Ok! So it seems that the additional patch is improving the situation. I
also fear that 1.1.0-rc2 is having the same error as 1.0.1 but is
swallowing it. I will investigate it further.

Regarding the efibootmgr error, I'm not really familiar with EFI. Can
you check that efivarfs is mounted as suggested here[1]?

Thanks,

Mathieu
