with stopping and disablement.
+ * UPGRADE ISSUE: a bug where some jobs were trimmed as redundant was
+ fixed, which in turn exposed bugs in unit configuration of services
+ which have Type=oneshot and should only run once, but do not have
+ RemainAfterExit=yes set. Without RemainAfterExit=yes, a one-shot
+ service may be started again after exiting successfully, for example
+ as a dependency in another transaction. Affected services included
+ some internal systemd services (most notably
+ systemd-vconsole-setup.service, which was updated to have
+ RemainAfterExit=yes), and plymouth-start.service. Please ensure that
+ plymouth has been suitably updated or patched before upgrading to
+ this systemd release. See
+ https://bugzilla.redhat.com/show_bug.cgi?id=1807771 for some
+ additional discussion.
