+Description:
+                A raw device name of a disk does not always point a same disk
+                each boot-up time. Therefore, users have to use persistent
+                device names, which udev creates when the kernel finds a disk,
+                instead of raw device name. However, kernel doesn't show those
+                persistent names on its messages (e.g. dmesg).
+                This file can store an alias of the disk and it would be
+                appeared in kernel messages if it is set. A disk can have an
+                alias which length is up to 255bytes. Users can use alphabets,
+                numbers, "-" and "_" in alias name. This file is writeonce.
