I know that you've already solved the renaming part, but I thought I'd
offer an explanation for this.

When anything is mounted on a directory, the directory becomes a /mount
point/.  That mount point is special in that it cannot be renamed or
moved, as it is "in use" by the filesystem which is mounted on it.

For future reference, here are commands for renaming/relabeling various
filesystems:

  * ext2/3/4: tune2fs -L <NEWNAME> /dev/foo
  * btrfs: btrfs filesystem label <NEWNAME> /dev/foo
  * FAT12/16/32: fatlabel /dev/foo <NEWNAME>
  * exFAT: ???

For ISO9660 and UDF, the filesystem names are set at creation.

These are just the ones I know.  I am sure that JFS, XFS, ZFS, etc. all
have their own commands as well.
