Yes the .d directory magic is awesome. Scripts are on purpose loaded in
alphabetical order.

I try to explain it with an example.

/etc/apt/apt.conf.d/10periodic comes with some Debian package. I don't
like the defaults for Whonix. The defaults in
/etc/apt/apt.conf.d/10periodic are.

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "1";
APT::Periodic::Unattended-Upgrade "1";

I created a file /etc/apt/apt.conf.d/20noperiodic with the content.

APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
APT::Periodic::Unattended-Upgrade "0";

2 comes after 1 in alphabet. Therefore 20noperiodic supersedes 10periodic.

apt-config dump shows, that it has been changed to my liking.

The advantage is, that I never have to fight with manually modifying
/etc/apt/apt.conf or /etc/apt/apt.conf.d/10periodic when the package
maintainer updates it.

With that knowledge I imagine, that the variables
GRUB_CMDLINE_LINUX_DEFAULT and/or GRUB_CMDLINE_LINUX from
/etc/default/grub could be extended using /etc/grub.d/somenumber_apparmor.
