The error message that is printed is misleading though, and gives the
impression that cd9660 filesystem support is missing:

	cd9660: No such file or directory

When mount(8) runs mount_cd9660, it gives it an argv[0] of the
fileystem type i.e. 'cd9660'. That's where the cd9660 in the error
message comes from. Maybe mount_cd9660 (and other mount_* programs)
should provide a bit more information in the error message?
