First and foremost, thank you for packaging OpenACS on Arch Linux.
For the people that support OpenACS Arch linux packaging here are a few notes:
1. /etc/naviserver/config-oacs-5.10.0.tcl
the db_name is oacs-5-9 should be changed to oacs-5-10-0 to match new database created.
2. /usr/lib/openacs - permissions default are root:root
should be nsadmin:nsadmin
chown -R nsadmin:nsadmin ./openacs/
Excellent job. :)
