Subject: [PATCH] core/manager: falling back to execute generators without
|
||
|
sandboxing
|
||
|
|
||
|
When running in a container, like podman, docker or so, creating new mount
|
||
|
namespace may be disabled.
|
||
|
|
||
|
Fixes #26474.
|
||
|
Fixes RHBZ#2165004 (https://bugzilla.redhat.com/show_bug.cgi?id=2165004).
