label with glabel or tunefs

[Omer Faruk Sen]

Hi, 

I am having difficulty why should I need to label a disk? I have read enough 
to understand the concpets of vinum. But in example at glabel man page a 
label created for just one disk (ad2). Why do I need to label just one disk? 


EXAMPLES
    The following example shows how to set up a label for disk ``da2'', cre-
    ate a file system on it, and mount it: 

	   glabel label -v usr /dev/da2
	   newfs /dev/label/usr
	   mount /dev/label/usr /usr
	   [...]
	   umount /usr
	   glabel stop usr
	   glabel unload 

    The next example shows how to set up a label for a UFS file system: 

	   tunefs -L data /dev/da4s1a
	   mount /dev/ufs/data /mnt/data 

 


I think my main issue is with the concept of  "disk labelization". Why one 
does need to create /dev/label/xxx or /dev/ufs/xxx instead of standard 
/dev/ad2s1a ..
