Restore /boot/efi to mtree.
Instead of whether /boot/efi exists, which it now always does, including
on systems that don't and can't use EFI, use whether /boot/efi is
present in fstab to signal to the installer that it is a valid ESP and
should be configured. This has essentially the same semantics, but allows
/boot/efi to be created unconditionally.
Sounds like the documentation about /etc/fstab content
should indicate the special/reserved /boot/efi usage
context, be that comments in initial default files or
whatever.
I wonder if anyone puts / at the end in an fstab: /boot/efi/
I tried using a trailing / in /etc/fstab and it is
one place were the notational variation is not
equivalent: I had to remove it.
FYI:
Reviewing/adjusting my /etc/fstab files I notice that
I have examples with things like:
/dev/label/Rock64boot /boot/efi msdosfs rw,noatime,noauto 0 0
#/dev/msdosfs/RPI4EFIFS /boot/efi msdosfs rw,noatime,noauto 0 0
Some might have a space after the #, shifting the
/boot/efi to be at $3 ? Some /etc/fstab files have both
types of /boot/efi lines (commented vs. uncommented),
associated with root-file-system-media that I move
between machines sometimes and toggle what is commented
(changing what media ends up referenced).
This change *only* applies to boot partitions created by the installer,
which have a well-known (to the installer) and controlled format.
As you note, though, there are a variety of ways someone could write
this in their fstab, which makes this approach tricky for updating, and
is why I originally preferred the simpler method of seeing whether the
mountpoint existed.
