What is the benefit to sharing $BOOT between different operating
systems/distros?
I'd like to point out that $BOOT doesn't have to be shared to dual-boot
multiple distros or benefit from other details of BLS.
But it's an awful mess... Whenever one OS updates or installs its boot
loader it tends to kick out all the others, unless it contains messy
scripts that try to find the other boot loaders first, and readds them
to the menu it's mostly luck if things work. With the bootloader spec
this is cleaned up, as it's built around drop-in files in a shared
directory, instead of exclusive last-writer ownership of the boot
loader.
Ultimately it just takes inspiration how RPM-based OSes nowadays
heavily rely on drop-in dirs so that lose coupling between packages
canbe implemented, as packages generally can't and shouldn't override
each other's files.
