+Subject: [PATCH] sgdisk: Run partprobe after partition changes
+
+The sgdisk tool does not update the kernel partition table in contrast
+to other similar tools. Often udev can detect the changes but not always
+as experienced when adding a new partition on Flatcar's boot disk.
+Instead of implicitly relying on some other component to re-read the
+kernel partition table, trigger the re-read with partprobe.
