lvm with -- on the name

Hi All,

I created an lvm filesystem with a name with dash in the middle, like xxx-yyy (note, that it's only one dash).

I was able to create it smoothly with this instructions.

lvcreate -L 1G uservg -n xxx-yyy
ls /dev/uservg/xxx-yyy (check)
mkfs.ext3 /dev/uservg/xxx-yyy
mount /dev/uservg/xxx-yyy /xxx-yyy

But when I do df-k, it will showed like this

/dev/mapper/uservg-xxx--yyy (note, that it have -- dash on it, double dash)

Is that okay? I got error when I'm not the root with doing the df -k of

df: `/xxx-yyy': Permission denied

Although the chmod is 775, it's still making an error like that on the permission.

But it's also okay, if the user owner or group owner will do the df -k, no permission error.

Is the - name allowed on the middle of the filesystem naming on lvm?

Any comment you may add will be highly appreciated. Thanks.

guards - select from a list of files guarded by conditions SYNOPSIS
guards [--prefix=dir] [--path=dir2:dir2:...] [--default=0|1] [-v|--invert-match] [--list|--check] [--config=file] symbol ... DESCRIPTION
The script reads a configuration file that may contain so-called guards, file names, and comments, and writes those file names that satisfy all guards to standard output. The script takes a list of symbols as its arguments. Each line in the configuration file is processed separately. Lines may start with a number of guards. The following guards are defined: +xxx Include the file(s) on this line if the symbol xxx is defined. -xxx Exclude the file(s) on this line if the symbol xxx is defined. +!xxx Include the file(s) on this line if the symbol xxx is not defined. -!xxx Exclude the file(s) on this line if the symbol xxx is not defined. - Exclude this file. Used to avoid spurious --check messages. The guards are processed left to right. The last guard that matches determines if the file is included. If no guard is specified, the --default setting determines if the file is included. If no configuration file is specified, the script reads from standard input. The --check option is used to compare the specification file against the file system. If files are referenced in the specification that do not exist, or if files are not enlisted in the specification file warnings are printed. The --path option can be used to specify which directory or directories to scan. Multiple directories are separated by a colon (":") character. The --prefix option specifies the location of the files. AUTHOR
