Comment 6 for bug 1244232

It seems that all the unmounted devices or what are marked "noauto" in /etc/fstab are being considered "Removable Devices" and listed in the connected part of the Removable Media system settings panel (Kubuntu) and are being mounted as per the "Enable Automatic mounting of removable devices" ("enabl...) selection. both partitions and LVM Logical Volumes are mounted.
When the "enabl.... Selection is disabled the file systems are not mounted (and the system does not hang on the disk icon during boot /auto login for the ~30 seconds).
Further testing comments:
When I plug in my usb drive it then is not auto mounted and must be mounted manually properly when "enabll... is deselected. When the "enabl.. is selected the usb drive is automatically mounted properly. Note: Even Though "Automount at login" and "Automount on attach" are deselected in the removable media panel they are mounted.
