  Modified files:
    usr.sbin/snapinfo    snapinfo.c 
  Imagine a situation where:
          # ls -ld /mnt/{foo,bar}
          drwxr-xr-x  3 root  wheel  512 Mar 16 06:56 /mnt/bar
          lrwxr-xr-x  1 root  wheel    3 Mar 16 12:10 /mnt/foo -> bar
          # grep /mnt/foo /etc/fstab
          /dev/da1        /mnt/foo        ufs     rw      0       0
  Which means, we give symbolic link as a mount point to mount(8), but mount(8)
  use realpath(3) before mounting the file systems, so we get:
          # mount | grep /dev/da1
          /dev/da1 on /mnt/bar (ufs, local)
  Before the commit:
          # snapinfo /mnt/foo
          usage: snapinfo [-v] -a
                 snapinfo [-v] mountpoint
          # snapinfo /mnt/bar
  This commit makes snapinfo(8) to first realpath(3) the given mount point and
  now we have:
          # snapinfo /mnt/foo
          # snapinfo /mnt/bar
