I've updated busybox to 1.7.2 and fixed the ash issue I noted earlier in this thread.

BusyBox v1.7.2 (2007-10-30 12:45:14 EDT) multi-call binary

BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable. Most people will create a
link to busybox for each function they wish to use and BusyBox
will act like whatever it was invoked as!

Currently defined functions:

I think the only way to install it and overwrite the existing is with an ipkg. I'll build one and do some testing later.
