The user needs to be made aware of that then. Otherwise, you'll have the=20
system upgrader overwrite your changes, potentially making the system=20
unbootable (without even being told that the grub configuration has been=20
reset).

Ideally, your app would manipulate the magic lines in the config files, and=
=20
then run update-grub where appropriate. That way you make sure that those=20
tools don't get in each others way. It *does* mean you have to have differe=
nt=20
ways of setting up the grub config file, based on the distribution (or do a=
ll=20
of them use the update-grub method by now ...)?
