Most of the tests should work on embedded platforms and with Busybox but
I personaly can't guarante that. In other words We are trying not to
break things for anybody, but some tests may not worked from the start.

As usual patches are welcome.

Sorry the LTP documentation is not in a good shape. On the other hand I
would be happy to include what you have found into the containers README
file. Just send a signed patch.

There are not. We have one archive to run on all flavors of Linux,
fragmentation would only make things worse.
