When mount command is executed in rootfs module of initrd, eudev creates a loop0 device node, applies rules and adds a inotify watch to it. Right after this step, we execute finish which first tries to kill any running udevd daemon before doing a switch_root. In some cases, it is possible that switch_root is executed before inotify_add_watch was actually processed which would lead to errors like: | inotify_add_watch(6, /dev/loop0, 10) failed: No such file or directory Make sure that we process all the events in queue before actually trying to kill udevd to prevent this race.

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.
