Subject: basic/audit-util: always log the reason when disabling audit logs
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=0c055d8d272d3043e66c276a2e5b57a95c447d6f;p=elogind.git

basic/audit-util: always log the reason when disabling audit logs

This state is cached, and it's seems OK to log at least once.

(cherry picked from commit 13bb68bbe37f0b39cd45234b09fb1a1da8302020)
