Hi Nicholas,

(i'm pasting in your queries as I'm not a subscriber and you didn't cc 
my address in your replies)

    What is the meaning of the $lvmignore keyword on this entry right
    below? It's the only time it appears here.
    And it's not present in your 2nd example that does work.

According to 
https://salsa.debian.org/installer-team/debian-installer/-/blob/master/doc/devel/partman-auto-recipe.txt

$lvmignore{_}
Used to void a partition definition so that it is ignored in the
LVM case. That is to say it will be valid in the default case.

Removing it did not affect the outcome...

    This may not be related, but notice also that the primary /boot
    which fails is an ext4 filesystem. But the example which succeeds,
    that one filesystem only is ext2, the rest are ext4 like yours.

Thanks for pointing it out; however the "working" recipe also succeeds 
with ext4 for /boot...

Antoine
