I'm running from the beta-2 kubuntu iso, and automount is disabled by default.

With locked luks:

Just after Decrypt and NO refresh. swap and root are not mounted at least
"mount" does not display them:
control luks-xxxxxxxxx ubu-root ubu-swap

Reading volume groups from cache.
Found volume group "ubu" using metadata type lvm2
NOTE: If I choose on KPM "Deactivate Volume Group" and I refresh the volume is
re-activated. This shouldn't happen because I didn't choose to Activate Volume
Group. Even more, there is no such option for that.
