rump_cd9660 [options] special node
In case mounting a file system image from a regular file, rump_cd9660 does not require the use of vnconfig(8) unlike kernel file systems. Instead, the image path can be directly passed as the special file path. The exception is if the image contains a disklabel. In this case vnconfig is required to resolve the start offset for the correct partition within the image.
It is recommended that untrusted file system images be mounted with rump_cd9660 instead of mount_cd9660(8). Corrupt file system images commonly cause the file system to crash the entire kernel, but with rump_cd9660 only the userspace server process will dump core.
To use rump_cd9660 via mount(8), the flags -o rump and -t cd9660 should be given. Similarly, rump_cd9660 is run instead of mount_cd9660(8) if ``rump'' is added to the options field of fstab(5).
Please see mount_cd9660(8) for a full description of the available command line options.
