You nailed it. I added “–attr-timeout 1s” to the string and it works fine. I also found that I needed to specify the cache directory since it is run from an interfaces script (as root). I should have realized this earlier as I have to specify everything else. I’m using sudo -u, but it still looks in the /root/ folder for everything, but runs as unprivileged.
Anyway, thank you for the tips.
