With kernels predating 6.3 the block size had to equal the page size to use 'verity'; with kernel version 6.3 this limitation was removed. However, the current LTS and SLTS kernels (6.1) predate this. At the same time, 'verity' is currently a set-only feature in tune2fs. This combination can cause problems with small partitions (like /boot) or 64k kernels (as on ppc64le, aarch64). Hence, the added note informs users about the previous kernel limitation.
