Yeah, I recall similar incidents many years ago. I don't recall the 
details, but wasn't there some HW/BIOS limitation (LBA?) ?

At least I haven't seen this happening for ca. a decade.

This will only work if the distros sharing their boot partition are 
similar enough and if these distros do not change their bootloaders.

History tells, you can get away with such a set up for some time, but in 
longer terms, one distro will trash the others' setup.
