I also just fresh installed a server with Parabola base-openrc and endwall.sh was spitting errors, I used another version of the file and it worked fine. I haven't tracked down the issue yet. I need to debug it by putting in echo statements. I'll do some more work on that later.

There are now open-rc scripts for most of what I need for server work including (postfix, dovecot, nginx, syslog-ng,squid, sshd etc) tor I compile and run from the shell, however ipsets doesn't have a script so I can't use this for a clearnet web or mail server yet.
