My actual custom stanzas are in /boot/grub2/custom.cfg, because I use only one
bootloader per PC, no matter how many installations it contains, which averages in
excess of 20, and I use whatever version of Grub2 that Tumbleweed provides,
usually the latest available. That shouldn't make any difference in Debian use,
other than the "2" in directory name.

In /etc/grub.d/ I copy 41_custom to 07_custom. Then I empty 41_custom and make it
immutable so that the entries 07_custom refers to are not duplicated by 41_custom
after every time whatever Grub package providing it is updated.

Manual editing of /boot/grub/grub.cfg does not persist. Every kernel addition or
removal causes its regeneration anew based upon the content of /etc/default/grub
and the regeneration script(s), same as running grub-mkconfig.

Details of 40_custom use I'm completely unfamiliar with, as I've never used it,
though I empty and lock it the same it as I do 41_custom.

I have only one set of custom entries per PC, those in /boot/grub2/custom.cfg.
It's such a long list that I normally don't see the automatically generated
entries before I've made a selection from among my own.
