/boot is specifically formatted with ext2 to maximize available
disk-space. As ext2 does not reserve space for journals, etc.
/boot is only used in lvm2/crypt setups. If you require for it to be
ext4, you can provide custom recipe to make sure it's formatted as
ext4 or upgrade to ext4 at post-install (e.g. by simply modifying
/etc/fstab and mounting it as ext4).

Are you sure that it's /boot that's causing problems? Because
ext2/ext3 are forward compatible, that is one can mount/treat it as if
it they were ext4. Thus it should not make any differences if
something is in fact ext2, 3 or 4 (especially for e.g. backup solution
which should access things read-only).

Title:
  hyper-v: Manual partitioning formats /boot with ext2 file-system

Status in “partman-auto” package in Ubuntu:
  Won't Fix

Bug description:
  Hi,

  It appears that if users manually partition the disk, the /boot
  partition is formatted using the ext2 file-system. This breaks certain
  backup scenarios for Hyper-V. Is it possible to change the default
  format for the /boot partition to ext4?

  Please let us know and see attached image for more details.
  Thanks,
  Abhishek
