Install a recent and un-crippled version of BusyBox.
BusyBox combines tiny versions of many common UNIX utilities into a single small
executable. It provides replacements for most of the utilities you usually find
in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer
options than their full-featured GNU cousins; however, the options that are
included provide the expected functionality and behave very much like their GNU
counterparts. BusyBox provides a fairly complete environment for any small or
embedded system.
