As I understand it you can already do this by changing # defoptions & altoptions line in /boot/grub/menu.lst. ea mine is: # defoptions=rootflags=data=writeback hdc=ide-scsi hdd=ide-scsi.

Now update-grub will add this options to the end of each kernel; this script is executed after a kernel update.

default was i think:
# defoptions=quiet splash
# altoptions=(recovery mode) single

if you change this to:

# defoptions=quiet splash noapic
# altoptions=(recovery mode) single noapic

If I understood you correctly I should think this change to /boot/grub/menu.lst should do what you want.

It has begun to drive me crazy that menu.lst is changed everytime I have a kernel update. For some reason, it always thinks my SATA is in a different place, and I always have to move it back, even though I have corrected device.map.

Seems like a simple thing to me, change only what you need to when you update the kernel.

Very important! I've installed a Pc to a friend that require the noapic option and after the first upgrade the pc don't start.

Voted down as this is easily done using the defoptions config option.

As it has been said, this can be done easily with defoptions option and such, but not all users find it right away when messing with menu.lst . Maybe add a clear help message there?
For example:
# If you want to add a boot option, consider adding it to defoptions, or it will be forgotten the next time a kernel update is installed.

And what about a GUI ?
