If mounts are left lingering, then after we switch_root, attempts to modify the block devices will result in an EBUSY with no way to unmount them. As we're about to switch_root anyways, there isn't much use to keep anything mounted unless it has the new rootfs.

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.
