Yes - this is a very good point. We have tried to ensure compatability 
by taking the following steps :

- Information about the image package contents comes from an XML file 
which is pregenerated and included
  in the image. So long as those creating a distro are capable of 
generating an XML file containing data about whatever sort of packages 
they are using then the C API will be able to use that data.

- We have made a clear separation between the C API as a data provider 
and the script used to actually install remove the packages. The did 
this because we are aware of the possibility that other Opensolaris 
releases may need to use different commands to install or remove content.

- We are also attempting to modularize the part of the code that read 
/var/sadm/pkg/SUNW*/pkginfo which is used for identifying packages on 
the system so that it can be overloaded/replaced easily for alternative 
packaging systems.

- I have mailed Glynn Foster requesting information about what way 
packaging is likely to work for Indiana. Last I heard it would be 
something very close to SVR4 but that might change.

- We have also explicitly flagged the dependency on /var/sadm/pkg in the 
one-pager as a consumed interface so ARC will also be able to highlight 
if this is likely to be a problem.
