I had it in /etc/init.d/local.start back when I used these features. |
| 12 |
Nowadays with openrc I would put this line |
| 13 |
in /etc/local.d/grub-default.start. I had some safety checks included, |
| 14 |
like testing if networking and sshd was running, so this box would be |
| 15 |
accessible from remote. But this is some years ago now, currently I do |
| 16 |
not administrate such remote servers and so I have not used this |
| 17 |
mechanism for a while. |

The first line in /boot/grub/default has the number of the default entry. |
| 24 |
grub-set-default modifies this file, as does the GRUB savedefault command. |
