[gentoo-user] udev-186 error messages after upgrade

Hi,

After upgrading to udev-186 I saw some errors when the service was restarted:

Jul 9 14:54:57 virtual udevd[30356]: unknown key 'RUN{builtin}' in
/lib/udev/rules.d/80-drivers.rules:10
Jul 9 14:54:57 virtual udevd[30356]: invalid rule
'/lib/udev/rules.d/80-drivers.rules:10'
Jul 9 14:54:57 virtual udevd[30356]: failed to create queue file: No
such file or directory
Jul 9 14:54:57 virtual udevd[30356]: failed to create queue file: No
such file or directory

I haven't rebooted it yet. Do you think it is safe to do so? I can't
find any clues about these errors. The rule mentioned in the first
error is unchanged from that contained in the systemd tarball. In
fact, they're all vanilla rules, I have no custom rules on this box,
and no /etc/udev/rules.d/ files at all.

Thanks,
Paul
