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.
