Exactly.
That was my take, too. It's udev's job to react to events generated by
the kernel and to set up things in user space (perms, symlinks, whatnot)
according to whatever policy the distro and the sysadmin have set up.
That's why the rules in /lib/udev (distribution) and /etc/udev (sysad,
override the distro's) exist. The kernel is no place to have those
rules, it's just the one enforcing them.
Layering, again :-)
