A bit more info: we're encrypted, and when it reboots, it can't find the tang server (using clevis/tang), so it hangs, and if I let it drop me to the emergency shell, I see the old IP address. I've been looking at this, and what's gotten really weird is that if I do a host tang on the server, it gives *two* different IPs... one of which has not been a dhcpd or tang server since last year. And tang<fqdn> is not in the organization DNS. So I'm sitting here, trying to figure out where it's getting both IPs from. Our dhcpd server knows the correct tang server. And the /etc/hosts on the server consists of 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 so it's not the hosts file. mark As I said, used the organizational lookup, and it doesn't find tang.
