Not at all. When there is a kernel update in main distro, it will generate a new /boot/grub/grub.cfg file. But /boot/grub/custom.cfg file does not change.oops wrote: ↑Mon Oct 15, 2018 4:08 amAh Ok, then sorry for the mistake. But if a kernel update is applied into your main distrib, you have to modify by hand your custom file?
And I don't need to change custom.cfg file in my main distro, since the entries in my custom.cfg file are made up only of chainloaders or entries which seek out and run directly the grub.cfg files of the other distros found on the other partitions.
Fehlix uses a similar system, and to have an idea of what is found in his custom.cfg file, see here:
