I just set up a new system where I have a dual boot of Win 7 along side Ubuntu 12.04.
My boot drive for both OS's is an SSD, and then I have mechanical shared storage (formated as NTFS).
In Ununtu, I need to install a few large applications including products from the Hadoop universe. I don't want to put all these on the SSD, but rather on the mech drive.
I managed to use Tweak to change the downloads directory, but can I somehow change the location where apps are installed to be on the mech drive so I save my SSD?
