When you edit GRUB is it permanent?

when the system starts
and you press escape to get to the GRUB menu
then e to edit
and b to boot...are those changes permanent? or is it just for that session? do you have to make changes in Grubd.conf or something for changes to affect every boot up?

thanks

If you make a change by pressing e to edit, it will only last until your next reboot. To make a permanent change, run the command

Code:

sudo gedit /boot/grub/menu.lst

substituting gedit with your favourite editor.

Only true for the deprecated and mostly unused Grub 1, aka Grub Legacy. With the newer Grub 2 you don't edit the configuration file directly, but you edit /etc/default/grub and the files in /etc/grub.d and after that use grub-mkconfig to create a new config file.

With my Grub 1 (CentOS) it's /boot/grub/grub.conf. I for one will keep with Grub 1 as long as it's available.
