To be entirely sure custom entries will always be present you should add
them to /etc/default/grub and then re-run 'grub2-mkconfig
-o /boot/grub/menu.lst' - this is the current "recommended procedure".
The background is that when you install kernels, grub.cfg is updated via
grubby, but if you want to manually re-generate the config, you use
grub2-mkconfig . grubby simply works by taking a copy of the first entry
in grub.cfg and adjusting it for the new kernel; grub2-mkconfig
re-writes the config from scratch based on the kernels it finds and the
other OSes it finds on your system. grub2-mkconfig reads 'extra'
parameters from /etc/default/grub , while grubby will simply 'inherit'
whichever others are currently present in entry #0 in grub.cfg .
So if you add them to /etc/default/grub and re-run grub2-mkconfig then
you'll know they're there on grub2-mkconfig runs, and because they're
now present in all grub.cfg entries, you know grubby will 'inherit' them
too.
/etc/default/grub is not currently packaged as a config file so changes
to it get overwritten when grub2 is updated; this has been reported as a
bug and should be fixed soon.
