Subject: [PATCH 153/165] tests: create 00confnames
|
|
|
|
The test is an attempt to document current implementation of devnode
|
|
and name handling for config entries. It is focused on incremental-
|
|
default way of array assembling on boot.
|
|
The expectations are aligned to current implementation for native
|
|
metadata because it is the most complicated scenario- both variables
|
|
can be set.
