+When no lockdir is present pkg is not enabled:
+  $ dune pkg enabled
+  [1]
+
+When the default lockdir is present pkg is enabled:
+  $ dune pkg lock > /dev/null 2> /dev/null
+
+  $ dune pkg enabled
+
+  $ rm -r dune.lock
+
+When a non-default lockdir is present, pkg is still enabled:
+  $ dune pkg lock dune.other.lock > /dev/null 2> /dev/null
+  $ dune pkg enabled
+
+Remove the other lock dir and make sure the status didn't latch to be always
+enabled.

+Manually enable package management in the workspace, it should be reported as
+enabled:
+
+  $ cat > dune-workspace <<EOF
+  > (lang dune 3.20)
+  > (pkg enabled)
+  > EOF
+  $ dune pkg enabled && echo "Yes, it is enabled"
+  Yes, it is enabled
+
+If we remove the setting from the workspace it should go back to the default
+(disabled)
+
+  $ cat > dune-workspace <<EOF
+  > (lang dune 3.20)
+  > EOF
+  $ dune pkg enabled || echo "Package management disabled"
+  Package management disabled
+
+Enable the package management globally in the user's config.
+
+  $ cat > config <<EOF
+  > (lang dune 3.20)
+  > (pkg enabled)
+  > EOF
+  $ dune pkg enabled --config-file=config && echo "Yes, it is enabled"
+  Yes, it is enabled
+
+Disable it in the user config, but enable it in the workspace. Workspace is
+higher precedence so it should be enabled:
+
+  $ cat > config <<EOF
+  > (lang dune 3.20)
+  > (pkg disabled)
+  > EOF
+  $ dune pkg enabled --config-file=config || echo "Successfully disabled by config"
+  Successfully disabled by config
+  $ cat > dune-workspace <<EOF
+  > (lang dune 3.20)
+  > (pkg enabled)
+  > EOF
+  $ dune pkg enabled --config-file=config && echo "Workspace config overrides user config"
+  Workspace config overrides user config
