Add warning about a potential hang on boot at devd after 20030507 if

you have an old kernel and a new userland.  I've just committed a fix
for devd to work around the kernel bug, but that goes away on May 7th.

+	A bug has been fixed in /dev/devctl which would cause devd
+	to hang on boot, were it not for a workaround in devd.  The

+	effects of this bug (hang on boot when starting devd), some
+	allowances are made.
