For a completely new installation, I want my Linux system to boot, and btsync to run, off a fast 64Gb USB3 flash drive in my USB3 port, while the data is stored on a 2TB spinning disk in my computer (Intel NUC Celeron processor). What is the best way to set this up, given that everything is starting from scratch? I have done the first part: install Debian Jessie 8.1 and btsync (using the Yeasoft repository version, now at v2). I set up my credentials within the web interface, and everything started working OK, but with the '/mnt' as the default folder location, which will be on the boot drive, of course. The flash drive is not nearly big enough to hold all my files, so I paused the installation. I tried to reset the 'default folder location' both in the debconf set up and in the web UI, but nothing worked, possibly because I don't know how to write the path to the internal drive for Linux. I feel like I am close, can anyone help?
