+Subject: [PATCH] remount: Still remount /sysroot writable if not configured ro
+
+Regression from https://github.com/ostreedev/ostree/pull/2113/commits/35642259175973617da937f3cab6ce5f13c95077
+BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1862568
+
+We still need to remount writable if it's not configured on;
+because it may need OS adjustments it needs to be opt-in.
