ugh, sorry, WAY too early in the morning.
If the installer needs a module in order to run, it has nothing to fall
back on to supply that module for it. Any surrounding client doing a
recursive installation can't fix it, unless what it can do when the
installer runs and says that the distribution itself needs dependencies.
This should be
"Any surrounding client doing a recursive installation can't fix it,
UNLIKE the way it can when the installer completes and tells the client
what needs to be installed".
If an installer can't INSTALL under battle conditions, it is failing
it's primary missing.
missing -> mission.
