Currently ZDEV_SITE_ID is derived with the help of an additional udev-rule, 40-zdev-id.rules. The sole purpose of this rule is to determine the ZDEV_SITE_ID environment value with the help of zdev_id binary. This solution is minimal, but this has some unwanted side- effects. The zdev_id logic get executed for all the events, even those completely unrelated to zdev/or site, and imports the unneeded envionment values to the udev-db. Instead of having an additional rule file, add this logic as part of the udev-rule of those devices which are configured with site-support. The logic will then be available on all those rules with the site-supported devices only.
