Subject: [PATCH 17/79] UTIL: Add wrapper function to configure logger
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
Let's use one enum for logger type instead of many integers (debug_to_file,
|
|
debug_to_stderr plus some weird combination for journald).
|
|
Old variable were also transformed to enum for backward compatibility
