+ (#4399)"
+
+RH-Author: Ani Sinha <None>
+RH-MergeRequest: 124: Revert "systemd: Standardize cloud-init systemd enablement (#4399)"
+RH-Jira: RHEL-21290
+RH-Acked-by: Emanuele Giuseppe Esposito <eesposit@redhat.com>
+RH-Acked-by: Cathy Avery <cavery@redhat.com>
+RH-Commit: [1/1] 10da53e761e25ff7d254a4cfb8fb1fd18de8b4ed
+
+This reverts commit ec7dde8041d4023b09324e84abe37dc766ebbaf6.
+
+'ConditionEnvironment' clause is not available in RHEL 8.10 systemd and adding
+the feature would be complicated. Hence reverting the patch seems to be the
+right thing to do as it was a simple enhancement to make sure all distros use
+systemd's kernel commandline and file conditionals. We only care about RHEL so
+the change should not affect us.
