If it's optional, then it ought to take precedence as far as owner/mode
issues are concerned, and IMHO owner/mode settings in the permissions file
should pass through symlinks to their targets ('scuse me, Greg!)

The only other complicating issue here, as far as Gentoo is concerned, is
the use of RC_DEVICE_TARBALL in /etc/conf.d/rc.  If this is turned on, I
believe that whatever is stored in it from the last shutdown pretty much
trumps everything as far as owner/mode issues are concerned, at least as far
as boot-time device config is concerned.  Until all device modules from all
vendors support sysfs then this may be necessary.  Red Hat and other distros
use other methods, but the issue is probably the same.

I use RC_DEVICE_TARBALL to store and retrieve VMware devices.  The VMware
devs have expressed their dislike for sysfs and don't want to work with it,
and unless one creates the devices manually or by some sort of script on
each system boot, they don't get created by the VMware kernel modules.
