wic allows the user to create disk image and reference each created
partitions via its partition UUID.
squashfs does not support filesystem UUID but it does offer support for
partition UUID.
$ lsblk -o NAME,FSTYPE,UUID,PARTUUID

Modifying this constrain allows a user to create squashfs-based rootfs and boot
from them with such kernel argument 'root=PARTUUID=7d46da2d-29cc-4d5a-9e39-d0381c4abb0c'

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
