Well, it seems to be working now - mostly. |
| 4 |
|

The fix was to write a new gpt label, create all the partitions and build a |
| 6 |
new system: no use of earlier packages. User data came from backups. |
| 7 |
|
| 8 |
Meanwhile, I used bootctl and efibootmgr to create and delete boot entries in |
| 9 |
the efi data until I finished up with this arrangement: |

|

# bootctl |

Note 1: I still can't 'bootctl install' without causing the damage I've |
| 59 |
described already. The system does boot though. |
| 60 |
|
| 61 |
Note 2: I've tried to change this with 'efibootmgr -b 00 -L "Gentoo Linux"', |
| 62 |
to no avail. It does nothing I can see. |
| 63 |
|
| 64 |
Note 3: This title comes from the file named two lines later; it has nothing |
| 65 |
to do with the Title of Note 2. |
| 66 |
|
| 67 |
Furthermore, when the default entry starts, I see 'SHA256 verified' in the |
| 68 |
upper left corner of the EFI BIOS display area, until the kernel takes the |
| 69 |
terminal over. |
| 70 |
|
| 71 |
Oh, and I deleted the unused directory (by me) /boot/EFI/systemd. |
| 72 |
|
| 73 |
So: solved, mostly. I still don't know what has changed though. |
