After trying to mount an nfs file system on my Crunchbang I got this error:

mount: wrong fs type, bad option, bad superblock on 10.1.1.1:/home/nfs,
       missing codepage or helper program, or other error
       (for several filesystems (e.g. nfs, cifs) you might
       need a /sbin/mount. helper program)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

All of this was because crunchbang does not come with nfs-common installed, so if run into this problem, run:

sudo aptitude install nfs-common

If you are working with Arch Linux, type this:

sudo pacman -S nfs-utils

And the problem will go.
