Re: mount by UUID or label

and then I tried it on my computer:

bmike1@c521 ~ $ sudo blkid
[sudo] password for bmike1:
/dev/sda1: UUID="f35e1797-4cdb-4930-a740-b424afbf61c7" TYPE="ext4"
/dev/sda3: UUID="7ca483d5-70b1-4449-a2dd-99d5ce8601f1" TYPE="ext4"
/dev/sda5: UUID="b45d28c4-edc6-4f9a-a80b-144e20197cf8" TYPE="swap"
bmike1@c521 ~ $ sudo mount -Lb45d28c4-edc6-4f9a-a80b-144e20197cf8 /mnt/sda6
mount: no such partition found
bmike1@c521 ~ $ sudo mount -Lb45d28c4-edc6-4f9a-a80b-144e20197cf8 /mnt/sda2
mount: no such partition found
bmike1@c521 ~ $

But then, as I was searching man just now, I think I found why it failed:

       Mount by label or uuid will work only if your devices  have  the
 names
       listed  in  /proc/partitions.   In  particular, it may well fail if
the
       kernel was compiled with devfs but devfs is not mounted.

and after looking into /proc/partitions see they aren't there. How could I
put the labels into /proc/partitions?

bmike1@c521 ~ $ cat /proc/partitions
major minor #blocks name

   8        0  244140625 sda
   8        1   24148992 sda1
   8        2          1 sda2
   8        3  214134784 sda3
   8        5    5855661 sda5
bmike1@c521 ~ $

Could I open a text editor and manually append them after sda? ?
