why does OE's systemd have a hard dependency on qemu-native?

why does OE's systemd have a hard dependency on qemu-native?

[Robert P. J. Day]

  currently messing with systemd-coredump and, in systemd_232.bb, i
see:

DEPENDS = "kmod intltool-native gperf-native acl readline libcap
   libcgroup qemu-native util-linux"
             ^^^^^^^^^^^ ?

now, i *am* building for qemuppc for testing, but the above is an
unconditional dependency on qemu-native. what does systemd need
qemu-native for?

  right below, we read:

    inherit ... qemu ...

so, again, qemu. yet a bit further down:

SRC_URI_append_qemuall = "
 file://0001-core-device.c-Change-the-default-device-timeout-to-2.patch"

so now SRC_URI is modified *conditionally* based on qemuall.

  can someone clarify what relationship systemd has with qemu?

Using the qemu class means you generally need to depend on qemu-native.

SRC_URI_append_qemuall = "

This is a MACHINE-specific tweak for qemu machines, and unrelated to the
qemu class.

Carry on searching for qemu:

pkg_postinst_udev-hwdb () {
        if test -n "$D"; then
                ${@qemu_run_binary(d, '$D', '${base_bindir}/udevadm')} hwdb
--update \
                        --root $D
                chown root:root $D${sysconfdir}/udev/hwdb.bin
        else
                udevadm hwdb --update
        fi
}

There is a rootfs-time postinst that uses qemu-user to run hwdb.
