Comment 3 for bug 2034206

I confirm, the "revision" files inside the "mysql_r188.charm" is "0".
It is actually zero inside all charms I have checked, constantly.

John, please correct my investigation:
 * long-long time ago Juju was generating both "version" (Git hash) and "revision". [1]
 * during migration to charmcraft, that functionality got lost. [2]

Your position: charmcraft/charmhub should generate file "revision" properly (non-zero). Correct?
