I think the wks file still has initrd=... in --sourceparams
which installs the initrd and a boot.conf.
With uki, only "loader=systemd-boot" needs to be there.

Not sure how kernel still got installed to /boot. Maybe
it's in IMAGE_EFI_BOOT_FILES?

Since uki.bbclass embeds the kernel command line,
wks file bootloader entry to append to command line
is not effective so --append="rootwait rootfstype=ext4"
should be UKI_CMDLINE now.
