our s390 sponsor pointed out a fix for 75-persistent-net-generator.rules
Created attachment 115749 [details, diff] udev-ccw-renaming.patch
>=udev-106-r4 contains this code: if use s390; then # s390 does not has persistent mac addresses # and we only have persistence rules for mac. # For now just remove the rules file. rm ${D}/etc/udev/rules.d/75-persistent-net-generator.rules fi Perhaps we just miss code in pkg_postinst to remove that rules from systems already having them.
i know you added that snippet to udev, the idea is that you can apply this patch and thus install the rule again
OK, will add it to next version/revision.
udev-114 contains extra s390 code for persistent-net.
