Hi Bill I see that initscripts in F18 ships this udev rule: ACTION=="add", SUBSYSTEM=="net", PROGRAM="/lib/udev/rename_device", RESULT=="?*", ENV{INTERFACE_NAME}="$result" I'm trying to tackle some problems related to interface renaming, and understanding how this works would be useful. But I can't find which software component *applies* the INTERFACE_NAME variable set by the above rule, actually performing the interface rename. Can you explain? FYI, I would imagine this area will also be susceptible to a current udev bug, https://bugs.freedesktop.org/show_bug.cgi?id=56929 Thanks Daniel -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
