I ran into this issue myself when using linux-libre-arm64-generic so
it's still around. It can cause boot problems too depending on what
exactly is missing.

qemu-binfmt-service-type adds a file-system dependency on
/proc/sys/fs/binfmt_misc, and requires the kernel to have
CONFIG_BINFMT_MISC set. The 6.8-arm64.conf file does have
CONFIG_BINFMT_MISC=m, but in the compiled kernel that option is unset.
Ergo the file-system doesn't exist and Shepherd fails to finish
initializing file systems.

Seeing as how certain config changes are made to
linux-libre-arm64-generic to improve device compatibility, I hope the
differences can be minimized between the "vanilla" linux-libre and
customized linux-libre-arm64-generic outside of device compatibility
changes to reduce surprises like this.
