[OE-core] [PATCH v3 0/5] systemd patches

[Richard Purdie]

Unfortunately this series failed in testing:

https://autobuilder.yoctoproject.org/typhoon/#/builders/72/builds/226

https://autobuilder.yoctoproject.org/typhoon/#/builders/56/builds/167

so it looks like it may need some tweaks before we can merge it.

Cheers,

Richard
