[PATCH] udevd - config cleanup
> Here is a small cleanup and better Makefile integration. > udevd and udevsender are now installed. Just switch HOTPLUG_EXEC from ROOT > to SENDER before install and udevsend will be called. > > We may add the location of the socket and lock file to the config, > if this is needed. Same patch with a fix for the stack size setting.
