+Subject: [PATCH 41/41] getty: grant checkpoint_restore
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Since Linux 6.7 checkpoint-restore functionality is guareded via the
+capability CAP_CHECKPOINT_RESTORE, with a fallback to CAP_SYS_ADMIN.
+Grant the new capability while keeping the old one for backwards
+compatibility.
