calibre-server demon won't load plugins

[genoasalami]

I'm running calibre-server 4.6 on FreeBSD, built from ports. The port comes with a startup script to run the server as a demon*. When the server is started this way, I cannot get custom plugins to load. However, when I manually simply run calibre-server from the command-line, everything is fine, and all the plugins load readily. This makes me think I'm missing something relatively simple, but I can't figure it out. I'd appreciate any help.

Here's the startup script:

rc.conf

#calibre settings
calibre_enable="YES"
calibre_flags="--disable-use-bonjour --auth-mode=basic --userdb=/usr/local/share/calibre/users.sqlite --enable-auth --log=/usr/local/share/calibre/logs/error.log --access-log=/usr/local/share/calibre/logs/access.log"
calibre_home="/usr/local/share/calibre/"
calibre_library="/mnt/library/"
calibre_user="root"
calibre_group="wheel"

startup script itself

* I recognize that this might be unsupported based on the fact the help options indicate that --daemonize is only support on Linux.

Do not run as root. And plugins are loaded from the calibre config directory, which defults to ~/.config/calibre and can be set via an environment variable see https://manual.calibre-ebook.com/cus...ment-variables
