Perhaps instead of making the template format dynamic based on fields,
as I suggested above, define a per policy rule template format option.

This should not be too complicated. The template to use will be returned
by ima_get_action() to process_measurement().

Some time ago I made some patches:

https://sourceforge.net/p/linux-ima/mailman/message/31655784/

Thank you for the reference!  In addition to Matthew's VFS hash use
case, Thiago's appended signature support would benefit from a per
policy rule template.  Do you want, and have time, to add this
support?

No problem. At the moment I'm busy with the digest lists patch set. I
will see if I have time later.
