.ipk are like debian (or indeed ubuntu) packages, i.e. they are
initially packaged with ar, not tar. Unpacking will give you a meta-data
file plus control.tar.gz. and data.tar.gz, which you can untar as usual.
data.tar.gz is meants to be untarred in /, i.e. it contains all folders
up from usr, var, etc.
