From f5c8c0911306661f062a8297eac0aee7deeac6f8 Mon Sep 17 00:00:00 2001 From: Cosmin Tupangiu Date: Wed, 18 May 2022 10:46:45 +0200 Subject: add tests and fix bug when char device pass the test as block device - add test - fix bug when a character device set in a volume as a block device is seen as block device in _pkg/specgen/generate/kube/volume.go_. At this stage the type does not matter much because the devices are recreated at lower layer but the bug allowed a CharDevice volume to be passed to lower layer as a BlockDevice.
