And I appreciate it.  As can be seen by the number of use cases already
supported by the integrity subsystem, it doesn't make sense for each
case to hash the file independently.

You've brought up some valid issues, which I'm trying to help you
address, but instead of working them through, your emails basically end
by saying "how is IMA going to deal with it" or "it's impossible".
Instead lets try to find viable solutions.

thanks,

Mimi
