[yocto] systemd support?

[Erik Botö]

Hi,

There's a bug in the bugzilla for this,
https://bugzilla.yoctoproject.org/show_bug.cgi?id=4843 . You can also look
at a mail thread,
http://lists.openembedded.org/pipermail/openembedded-core/2013-June/080328.html
for
some more context.

If you just want to get past it you can do something like the below. It's
not a real fix but a work around.

diff --git a/meta/classes/qemu.bbclass b/meta/classes/qemu.bbclass
index 3d437b0..0f6e882 100644
--- a/meta/classes/qemu.bbclass
+++ b/meta/classes/qemu.bbclass

     libdir = rootfs_path + data.getVar("libdir", False)
     base_libdir = rootfs_path + data.getVar("base_libdir", False)
-    return "PSEUDO_UNLOAD=1 " + qemu_binary + " -L " + rootfs_path\

             + rootfs_path + binary


Cheers,
Erik Botö
