Yesterday I did a buildworld and an installworld with sources which
contain the fixed routing code (cvsup at ~3pm CET). Today I tried to
dialout-on-demand right after boot. I use ISDN and have
defaultrouter=3D"-interface isp1"
in my rc.conf. It didn't worked and I found the reason withhin a minute.
There wasn't a defaultroute. So I just added the defaultroute and
everything was fine... until the next time my system tried to
dialout-on-demand. There wasn't a defaultroute again. Boring. Ok, I just
added the defaultroute again and the system dialed out. After this
second "route add default -interface isp1" the defaultroute didn't
disappeared for several dialouts. I haven't rebooted yet to try to
reproduce it.
Perhaps some interesting facts:

[Yes, it's down at the moment, I didn't want to dialout at the moment.]

Don't worry if this problem is solved by the commit which fixed a PR
(I've seen it on cvs-all, but hadn't time to have a look at it).
Bye,
Alexander.

It's not a bug, it's tradition!
