Dovecot setup incompatible with full text search

Was this an apt install or from their github? I see Debian has it as a package but I got ‘inconsistent’ results searching for an Ubuntu package.

Also, I think by default I had to change WHERE the control files were stored. I think they defaulted to /var/… to keep folks from messing up their mailboxes. The server I was moving from had them already in the user directory so I kept them there. Is this a problem for the plugin?
