From 62663fb7ec191ca2f872aec1636e94934212936f Mon Sep 17 00:00:00 2001 From: Richard Laager Date: Sat, 30 May 2020 20:39:31 -0500 Subject: Fix another dependency loop zfs-load-key-DATASET.service was gaining an After=systemd-journald.socket due to its stdout/stderr going to the journal (which is the default). systemd-journald.socket has an After (via RequiresMountsFor=/run/systemd/journal) on -.mount. If the root filesystem is encrypted, -.mount gets an After zfs-load-key-DATASET.service. By setting stdout and stderr to null on the key load services, we avoid this loop.
