An official ppa repository for Ubuntu would be great!
There is a link to an unofficial one in your page, but since this is a security app, installing it from some random repo just feels wrong... Thank you for the great work!
I would try the symlink approach for now. Possibly drop a file next to the DB on your share in case you have to do it again and don't remember.
EDIT: Wait, now it's downloading a second 80 MB container :(
