Sorry, Stefan. This was supposed to go to the list.

All my machines have a separate /boot partition (and everything
else in LVM). These are all "historical accidents", because at the time
I set them up, the respective boot loader (LILO, Grub, U-Boot) didn't
know how to read LVM volumes, and I just never bothered to change.
But I fully agree with you: if your bootloader can read from LVM
(as is the case with Grub2), then you're better off without a separate
/boot partition.
Stefan "not sure if U-Boot can read from LVM yet"
I am primarily running Devuan, these days, but I also still have
root/boot partitions (boot is not separate from root) for Stretch and
Buster. My /boot directory contains 4 kernels and their associated
files and the whole lot only takes up about 140MB. Since I use Lilo as
my boot loader (and it can read LVM), and I don't use encryption, I
can put everything (including root/boot) into a single LVM physical
volume. No hassles if I need to resize any partition, since they are
all logical volumes in a single volume group on a single physical
volume. If I ever need more total space, which I find unlikely, I can
add additional disks to the PV and then add space to any LVs as needed.
