firewalld runttime to permanen error

[Charles Curley <charlescurley@charlescurley.com>]

I've just installed Debian 12 on a new machine. I'm setting up the
firewall with firewalld. I have two interfaces (and lo). I'd like to
change the zone of one of them from "trusted" to "home". I can do that
in the runtime, but when I go to make that change permanent, I get a
vague error message:

root@issola:~# firewall-cmd --runtime-to-permanent
Error: RT_TO_PERM_FAILED
root@issola:~#

-- 
Does anybody read signatures any more?
