"""
we have recently discussed the matter of systemd-boot in

an upstream shim review gathering.

We reject a signing of systemd-boot as

* systemd-boot does not use current ways of communicating with
  shim

* There was some concern over general quality

* systemd-boot is an additional bootloader, rather than replacing
  an existing one, thus increasing the attack surface.

  If people want to experiment with other bootloaders than the
  default one, they can disable secure boot, or load their own
  keys into the machine. We do not consider it valid to have
  a choice of bootloaders.

I want to note that the current shim has been signed with the
understanding that it will trust grub, kernels, and fwupd. A
signing of systemd-boot might be considered reasons for revoking
the existing shim, and will certainly result in new shims not
getting signed.
