+What's wrong with this? It's showing you the mounts that are active...
+would you rather it filtered out e.g. /sys etc?
+
+There are other commands you can use other than mount... e.g. df
+
+[colin at jimmy ~]$ df
+Filesystem                                 Size  Used Avail Use% Mounted on
+rootfs                                      15G   12G  2.1G  85% /
+devtmpfs                                   1.6G     0  1.6G   0% /dev
+tmpfs                                      1.6G  804K  1.6G   1% /dev/shm
+/dev/mapper/solidstate-slash                15G   12G  2.1G  85% /
+tmpfs                                      1.6G  3.2M  1.6G   1% /run
+tmpfs                                      1.6G     0  1.6G   0%
+/sys/fs/cgroup
+tmpfs                                      1.6G     0  1.6G   0% /media
+/dev/mapper/solidstate-home                130G  128G  1.6G  99% /home
+/dev/sda2                                   85M   47M   34M  59% /boot
+
+
+Generally speaking df is a more useful command than mount IMO anyway,
+and it's always been the command I use when I'm just wanting a quick
+overview.
