Morning all, |
| 2 |
|
| 3 |
I'm trying to set the default boot entry via bootctl or efibootmgr. I know I |
| 4 |
can set it directly by pressing D at the boot selection screen, and the system |
| 5 |
does boot properly; I just want to understand the setup a bit better. I don't |
| 6 |
have the rest of systemd: this is an openrc box. |

Default Boot Loader Entry: |
| 49 |
title: Gentoo 5.4.48 (No network) |
| 50 |
id: 44-gentoo-5.4.48.nonet.conf |
| 51 |

| 52 |
|
| 53 |
44-gentoo-5.4.48.nonet.conf is the last entry in /boot/loader/entries. |
| 54 |
|
| 55 |
Man bootctl says: |
| 56 |
set-default ID, set-oneshot ID |
| 57 |
Sets the default boot loader entry. Takes a single boot loader entry ID |
| 58 |
string as argument... |
| 59 |
|
| 60 |
But then, |
| 61 |
# bootctl set-default 30-gentoo-5.7.7.conf |
| 62 |
Failed to update EFI variable: Invalid argument |
| 63 |
|
| 64 |
...in spite of this: |
| 65 |
# cat /boot/loader/entries/30-gentoo-5.7.7.conf |
| 66 |
title Gentoo 5.7.7 |
| 67 |
version 5.7.7-gentoo |
| 68 |
linux vmlinuz-5.7.7-gentoo |
| 69 |
initrd=intel-uc.img |
| 70 |
options root=/dev/nvme0n1p4 net.ifnames=0 raid=noautodetect |
| 71 |
|
| 72 |
...and this: |
| 73 |
# mount | grep efi |
| 74 |
efivarfs on /sys/firmware/efi/efivars type efivarfs |
| 75 |
(rw,nosuid,nodev,noexec,relatime) |
| 76 |
|
| 77 |
I've also tried telling efibootmgr to set the default. |
| 78 |
|
| 79 |
# efibootmgr |
| 80 |
BootNext: 0007 |
| 81 |
BootCurrent: 0007 |
| 82 |

Efibootmgr -n 7 seems to make no difference, as expected, but: |
| 92 |
# efibootmgr -N 7 |
| 93 |
Boot entry 0001 does not exist |
| 94 |
# cat /boot/loader/loader.conf |
| 95 |
default 30-gentoo-5.7.7 |
