The answer appears to be "No" but I don't see this discussed in the KB or docs, so let me throw this out here:
When you assign an install package to a group (Clients Page, Install Packages tab) are these packages supposed to be inherited by subgroups (assuming inheritance isn't blocked)? The GUI imples that they should be inherited, but it doesn't seem to work that way (they never show up in the sub-groups)...
