Bug#1020396: systemd-boot: kernel installation/initrd update hooks double the initrd like #970213 since #826045

[наб]

Hi!

Wrong MR; actually 170:
  https://salsa.debian.org/systemd-team/systemd/-/merge_requests/170

And I forgot the patches. Thankfully, I came up with a much better way
of fixing this: since systemd v251 we can just copy the initrd.img-$KVER
to $KERNEL_INSTALL_STAGING_AREA, and 90-loaderentry will install and
verison it properly ‒ we never have to generate a bare "initrd" in the
first place!

Actually attached them this time :)

Transcript of installation with patched system follows.

Best,
наб
