vfat/msdos filesystem should have fsuuid in format 0xYYYYYYYY where "0x" in front follow with 8 hexadecimal number in uppercase. In wic, when using custom fsuuid for vfat/msdos partition in wks, it is able to set the value in any length, with or without leading "0x". This can cause fsuuid missaligned when fstab updates, fstab expect exactly 10 character fsuuid for vfat/msdos partition and all in uppercase. if custom fsuuid for vfat/msdos is set, check the length and format, error if it exceed the format size. Amend it so it is align with format 0xYYYYYYYY. This is done before image create and fstab update to ensure the fsuuid are same in all followup process. if custom fsuuid length less than expected, fill in "0".

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.
