Re: Migrating to Grub2 deletes kernel automagic updates and other settings

They may or may not be an os-prober package but when it comes to grub,
os-prober is a script in /etc/grub.d (/etc/grub.d/30_os-prober). If it
is executable, it will add the kernels that it finds to
/boot/grub/grub.cfg when update-grub is run.

I do the same. All my entries are in 40_custom and 10_linux and
30_os-prober are not executable.
