The user should select the hwpack that corresponds to the revision of
the Snowball targeted. That is lt-snowball-v2 or lt-snowball-v3. The
combined hwpack which is simply called lt-snowball contains packages for
both v2 and v3 and then the files clash on install.

I agreed a while back to investigate how much work it would be to make
l-m-c handle duplicates of packages like this. I wanted more info on the
changes needed for Snowball V5 though, so we don't fix the problem now
and need another fix when the new revision arrive.

So this kind of hwpack is not supported by the tools. We would need to
implement the snowball_v2_emmc and snowball_v3_mmc --dev options for
this to work. I think a prerequisite would be for the different
startupfiles debs to install the files to different paths so that they
do not clash on install.

** Summary changed:

- Snowball hwpack V1 (20110905) fails with l-m-c
+ Combined V2/V3 Snowball hwpack (20110905) fails with l-m-c
