tree output at both efi partitions
The UEFI only shows one efibootmgr-manual entry, either at the boot selection
screen or system setup. It does not boot.
Nothing from OpenSUSE was installed at the hard drive, and actually, as I said
above, disabling the HDD and creating the boot entry by just running Yast
bootloader does create a boot entry pointing to the right disk. Until I enable
it again.
Attached session: a text file containing the output of tree for /dev/sda1 and
/dev/nvme0n1p1
Those files seems to be where they are supposed to.
