From 0b2c9c2acc38f51f871fd5a06aca205127a06d1d Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Mon, 29 Apr 2019 10:37:50 -0400 Subject: Add basic structure of podman init command As part of this, rework the number of workers used by various Podman tasks to match original behavior - need an explicit fallthrough in the switch statement for that block to work as expected. Also, trivial change to Podman cleanup to work on initialized containers - we need to reset to a different state after cleaning up the OCI runtime.
