[Bug 1797894] [NEW] upgrading grub, modifies GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub

[Dimitri John Ledkov]

Public bug reported:

upgrading grub, modifies GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub

if one has makedumpfile installed. the setting from /etc/default/grub.d
/kdump-tools.cfg which imho should not have leaked into
/etd/default/grub.

See screenshot.

Also,

grub-efi-amd64  grub2/linux_cmdline_default     string  quiet splash
pcie_aspm=off crashkernel=512M-:192M

has been helpfully "updated" when it should not have.

in postinst, it seems like we source all of /etc/default/grub.d/* files,
when maybe we should not have.
