> 2. transactional-update initrd doesn't work together with systemd-boot

Correct, currently systemd-boot is not directly integrated into
transactional-update itself yet (i.e. the commands "initrd", "bootloader" and
"grub.cfg" don't do the right thing on a systemd-boot system).

systemd-boot support is generically implemented as a snapper plugin using the
"sdbootutil" instead, because of course you can also use systemd-boot on
non-transactional systems. The sdbootutil script also includes detection
whether it is necessary to regenerate the initrd.

@Alberto: On a first glance I couldn't find any RPM macro integration so that a
RPM package calling %regenerate_initrd_post would trigger the initrd rebuild on
a systemd-boot system. Am I missing something, or do we still have to implement
this?

See answer above - this is something which needs to be implemented on a RPM
macro level...
