Issues with cpio.lzma as well:

| ln: failed to create symbolic link
`/oe/oe-core/build/tmp-eglibc/deploy/images/initramfs-kexecboot-klibc-image-poodle.cpio.lzma':
File exists

Looking at run.do_rootfs I see runimagecmd is called twice.

In the log.do_rootfs there is also a strange

+ sed sERROR: Function failed: do_rootfs (see
/oe/oe-core/build/tmp-eglibc/work/poodle-oe-linux-gnueabi/initramfs-kexecboot-klibc-image-1.0-r0/temp/log.do_rootfs.31195
for further information)
/generic_//g
