 * Live CD has to run in RAM, so `rd.live.ram=1` is set for cmdline. Otherwise, at least on my ancient flash drive, it fails to load multiple necessary services, including `polkit`.
 * No rescue vmlinuz.
 * No secure boot possible for this ISO for now, as the platform used is `efi` and not `uefi`.
-* No GRUB auto hidden menu. Trying to have the menu hidden results in system simply crashing after trying to boot it.

+* No hardware video decoding for now, as the iris video codec (`qcvss8380_pa.mbn`) is Windows-only (as far as I researched), but you can copy one to `/lib/firmware/qcom/x1p42100/Microsoft/Surface12/`, if you have Windows ARM64 partition.
