Document that the administrator should delay purging the master key until after propagation and some daemon activity. ticket: 8744 tags: pullup target_version: 1.17 doc/admin/database.rst | 4 ++++ 1 files changed, 4 insertions(+), 0 deletions(-) diff --git a/doc/admin/database.rst b/doc/admin/database.rst index 14c145b..2b02af3 100644 --- a/doc/admin/database.rst +++ b/doc/admin/database.rst @@ -535,6 +535,10 @@ availability.
