When polkit is not available, networkd will not have permissions to call hostnamed's dbus methods, as it runs without privileges. To solve this, when building without polkit, make a new PACKAGECONFIG 'polkit_hostnamed_fallback' available which changes hostnamed so that it runs as the 'systemd-network' user, the same as networkd, so that the authorization works (and also with CAP_SYS_ADMIN since it loses root). Also run it with a separate 'systemd-hostname' group which also owns the bus, to avoid giving the 'systemd-network' additional privileges.

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.
