There is a 4th option to the 3 options above, which is changing the specific folder at /var/lib/pgsql/10/data and allow it to become persistent in in this location /rw. The /rw folder stays persistent, and it's also here you'll find everything else that is staying persistent in the AppVM's. Changing what stays persistent and what doesn't is actually quite easy to do too, but be aware it adds yet another folder which can be exploited to attacks, so if you can use the option 1) awokd mention up above, then it'll be more secure. Basically how it works, is that it'll start the full template, then it'll remove the symbolic links to the specific folders you want to be persistent (that means, the default template folders are cut-away), and then it'll change the symbolic link to the persistent folder. Generally, I believe, this is how AppVM's work in general, however, you can modify it to include or exclude specific folders, as you desire. Use a terminal text editor, like nano, and edit this file '/rw/config/rc.local' Instructions how to do this is included in the Qubes file, it's using Cups as an example how to do it, just do the same for your specific folder instead of Cups. Remember the systemctl restart is only needed if you're changing a service or module driver, it might not be relevant for your needs. So you only need the "rm" template folder line, and the "ln -s" add new symbolic link line to a replacement folder. Remember your "/var/lib/pgsql/10/data" content, now will be inside a folder you placed somewhere suitable in the /rw folder, for example /rw/var/lib/pgsql/10/data, which then will act as if it was at the real destination. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
