Bug#979386: debian-installer: Install Annoyance

[Mike McCulley <solitaire@centurylink.net>]

Package: debian-installer
Version: buster
Severity: normal

Dear Maintainer,

I have a triple-boot setup so GRUB and swap both exist, and that creates the
annoyance.

Debian installer displays messages about the necessity of having GRUB
installed, which implies it's possible to not install GRUB, but that option is
not available. After installing Debian it's necessary to boot the primary OS
and reinstall the custom GRUB. Life would be better if there was an option to
skip the 'install GRUB' step.

Debian installer formats swap, which changes the UUID, and not formatting is
not an option. After installing Debian it's necessary to edit any other fstabs
and update the swap UUIDs. Life would be better if there was an option to not
format swap.
