Yes, that's what I see too.

Generally, it's no big deal, apart from making the router take a little
longer to boot up.  But if you have a hardware problem on the router
and the image on disk0: isn't readable, you'll boot up in the monitor
rather than in the bootflash IOS.  You can still recover the router, but
it might be harder, take longer, or (eek) require a remote visit.
