Subject: [PATCH] journalct: allow --boot=0 to DTRT with --file/--directory |
|
|
|
--boot=0 magically meant "this boot", but when used with --file/--directory it |
|
should simply refer to the last boot found in the specified journal. This way, |
|
--boot and --list-boots are consistent. |
|
|
|
Fixes #3603. |
|
|
|
(cherry picked from commit 592855c3189549fed93b1060b72299910c6ab1d0) |
