Do I need to repeat that I did no suggest to revert the /boot partition 
to ext2  on arm64 ? I found other evidence that Petitboot supports ext4:

<https://discourse.nixos.org/t/newbie-installs-nixos-on-an-arm-sbc-or-how-patience-is-a-virtue/35020>
Odroid ARM64
"Additionally when making a new installation, Petitboot supports ext2, 
ext3 and ext4 and a couple other filesystems like vfat and iso9660, so 
/boot should be on one of those."

<https://forum.odroid.com/viewtopic.php?p=251632>
Odroid ARM64
"OS in the memory card can boot from Petitboot if the type of the root 
file system is ext2/3/4."

This one is even more interesting:

PS3 POWER
"I noticed that petitboot can boot from ext4, but only if it was created 
inside petitboot itself. For some reason if I create it using Gentoo, 
petitboot is not able to mount it. What could be the difference that 
makes it unsupported?"

Maybe some Petiboot instances use older kernels which do not support new 
ext4 features enabled by default in more recent e2fsprogs ?
