I read through this and couldn't work out its relevance. My boot
partition doesn't contain any hard links: the link counts are all 1.
The problem mentioned in the bug report (hard links are necessary to
conserve space) would be irrelevant as there's so little demand for
space in /boot.

Now I think I can see the temptation to put all of /boot into the ESP:
mine contains a tree of files under grub/ plus the eight kernel files
one would expect—nothing that appears to conflict with a VFAT
filesystem—so the EFI directory would fit nicely there.

Examining the real ESP on this PC, I don't see any potential for name
clashes between the windows files in there and what Debian users
report is in their own ESPs (which appear to be safely stowed under
the directory debian/).

So what are the arguments against doing this (which I accept there may
well be)? We'll ignore the eyebrow-raising need for /boot to be
journalled, shall we?

Cheers,
David.
