What this command does is basically showing the
content of the file 'mtab':
If you want to check the content of this file yourself,
type on the command line:
  cat /etc/mtab
---
---
Note: so e.g. the entry
 /dev/scd0 on /mnt/cdrom type udf (ro)
is clearly missing.
---
---
Method: use the 'dir /mnt' command:
if you type the command:
 dir /mnt
this will show the block devices that are currently mounted
---
e.g. in Linux v7.3 you will see:
floppy disk cdrom
---
e.g. in Linux v9.0 you will see:
cdrom flash floppy hgfs
---
---
Method: use the 'df' command:
---
df = Disk Free
---
if you type the command:
 df
this will show e.g. the following on my computer,
using Linux Red Hat v9.0:
-------------------------------------------------------------

-------------------------------------------------------------

on another computer it showed,
using Linux Red Hat v9.0:
-------------------------------------------------------------

After a CD was put in, and the CDROM mounted the same computer
showed:
---
-------------------------------------------------------------
