libudev-zero recipe issue

Hi all,

I added a new recipe for libudev-zero, which provides a minimal daemon-less udev implementation. The recipe works, but has an issue that pops up regularly where it causes an exception during rootfs:

Exception: FileNotFoundError: [Errno 2] No such file or directory: '/ssd/opt/oe/yocto/kirkstone/build-weston/tmp-glibc/deploy/ipk/core2-64/libudev1_1.0.2-r1_core2-64.ipk' -> '/ssd/opt/oe/yocto/kirkstone/build-weston/tmp-glibc/work/generic64-oe-linux/sollinux-ble-weston/1.0-r0/oe-rootfs-repo/core2-64/libudev1_1.0.2-r1_core2-64.ipk'

It seems like for some reason the ipk has been removed from deploy/ipk. To recover from this, a 'bitbake -c clean libudev-zero' will restore things the next time the rootfs is run.

Does anyone have an idea what could cause this? Appended below is the recipe, and the full error message.

Cheers,

Rob
