mount gives:

/dev/hda2 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/hda3 on /home type ext3 (rw)
/dev/hda5 on /usr/local type ext3 (rw)
usbfs on /proc/bus/usb type usbfs (rw)

and /etc/fstab says:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/hda2       /               ext3    defaults,errors=remount-ro 0    1
/dev/hda3       /home           ext3    defaults        0       2
/dev/hda5       /usr/local      ext3    defaults        0       2
/dev/hda7       none            swap    sw              0       0
/dev/hdc        /media/cdrom0   udf,iso9660 ro,user,noauto  0       0
/dev/hdd        /media/cdrom1   udf,iso9660 ro,user,noauto  0       0
/dev/fd0        /media/floppy0  auto    rw,user,noauto  0       0
/dev/sda1        /media/usb0    vfat    user,rw,umask=000     0     0/

As you can see there is no mention of either /mnt or /dev/hdb2.
