Any way to permanently save an edited entry in a GRUB menu during GURB menu usage, not after the system have booted and i can do that by a myriad a ways.
I know about editing the config scripts in
grub.d, but for quick changes while I'm fixing something, and that I will have to boot into some ten times and then never more, i'd love to be able to edit an entry on the spot and save.
The manual does not mention anything else besides what's already mentioned on the edit screen (i.e.
esc cancel edit), but then, I had to find most available commands from the emergency prompt outside of the manual.
