I'm not sure if this is a bug or expected behaviour...

I was installing Solaris over network, so on my NetBSD-current I mounted
Solaris DVD on /cdrom then put this directory in /etc/exports and restarted
mountd.

After the install, I ran 'umount /cdrom', ejected DVD and inserted a CD-RW.=
 But
now running the following command fails:

ultra10# cdrecord -v dev=3D/dev/cd0c blank=3Dfast

NOTE: this is OSS DVD extensions for cdrtools and thus may have bugs
   related to DVD issues that are not present in the original cdrtools. For
   more information see http://crashrecovery.org/oss-dvd.html. The original
   cdrtools author should not be bothered with problems in this version.

However the following command succeeds when I substitue device name with nu=

Anyone knows what's going on here? This is sparc64 so /dev/cd0c is the enti=
