From 592855c3189549fed93b1060b72299910c6ab1d0 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Tue, 28 Jun 2016 16:12:47 -0400 Subject: 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.
