init - sysvinit vs BusyBox

[Shay Hofman]

A novice question -

Is it possible to tweak and change busybox on an existing embedded device?
To be exact I'm referring to  Dlink home router device which has a very
limited and stripped down busybox os.
Very few linux commands can be executed...

What are your thoughts / experience ?

Thanks
Shay
