If the device is not a CD-ROM, 113or the table of contents cannot be examined, the file system will be 114started at sector 0. This option can be used to override the behaviour. 115Note that 116.Ar startsector 117is measured in CD-ROM blocks, with 2048 bytes each. This is the same 118as for example the 119.Cm info 120command of 121.Xr cdcontrol 1 122is printing. 123It is possible to mount an arbitrary session of a multi-session CD by specifying 124the correct 125.Ar startsector 126here. 127.It Fl v 128Be verbose about the starting sector decisions made. 129.El 130.Sh EXAMPLES 131The following command can be used to mount a Kodak Photo-CD: 132.Pp 133.Dl "mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom" 134.Sh SEE ALSO 135.Xr cdcontrol 1 , 136.Xr mount 2 , 137.Xr unmount 2 , 138.Xr fstab 5 , 139.Xr mount 8 140.Sh HISTORY 141The 142.Nm 143utility first appeared in 144.Bx 4.4 . 145.Sh BUGS 146POSIX device node mapping is currently not supported. 147.Pp 148Version numbers are not stripped if Rockridge extensions are in use. 149In this case, accessing files that don't have Rockridge names without 150version numbers gets the one with the lowest version number and not 151the one with the highest. 152.Pp 153There is no ECMA support. 154
