It shouldn't need to be set for every driver, wireless doesn't work this way, so there is lots of precident for how to do this in only a few lines of kernel code :) > Also, if we start setting DEVTYPE=ethernet in the kernel, I guess apps > (such as connman) that relies on DEVTYPE=(null) to detect ethernet > devices will break. Ah, that's a different problem, we can't break userspace. Ugh, well, if you want me to try to make this change, I will. thanks, greg k-h _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
