Yep. ifcfg-em1 is set to dhcp.
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.

As I said, used the organizational lookup, and it doesn't find tang.
