This patch fixes a bug where the udev database stored empty strings for Owner and Group if they were default. This patch stores the default value into the database if not set otherwise. See example output: crw------- 1 root root 4, 65 Jan 16 11:13 ttyS1 P: /class/tty/ttyS1 N: ttyS1 S: O: root G: root This is a bit of a hack. However, until udev supports setting the o/g values they will be root/root anyway so the database might as well reflect the truth instead of empty strings.
