trouble mounting cdrom

[John Clyne]

I just installed ultrix 4.2 from cdrom. Thank you digital for not providing
an upgrade from 4.1 to 4.2. Doing a complete install really made my day (or
night i should say). After the installation i wanted to load all of our 
unbundled software. Alas i was unable to mount our lovely new RRD40. If
I execute

	% mount /dev/rz4c/mnt

i get

	ufs_mount: /dev/rz4c on /mnt: Restricted operation on file system

If i execute

	% mount -t cdfs /dev/rz4c /mnt

I get

	cdfs_mount: Unknown descriptor type

Yes i do have

        options CDFS
        pseudo-device    cdfs

configured in the kernel.


Any ideas? 

thanks much - jc
