I am running a simple workstation, connected to a consumer-grade router by an ethernet cable. I didn't (and don't) have a specific configuration for enp38s0. I did $ rc-update del net.enp38s0 default and rebooted. The machine came up without error messages, indeed with fewer messages than it used to. On tty1, I now see just: INIT: Entering runlevel: 3 * Checking your configfile (/etc/syslog-ng/syslog-ng.conf) ... * [ ok ] * Starting syslog-ng ... * [ ok ] * Starting DHCP Client Daemon ... * [ ok ] * Setting clock via the NTP client 'ntpdate' ... * [ ok ] * Starting cronie ... * [ ok ] * Starting dbus ... * [ ok ] * Starting cupsd ... * [ ok ] * Starting gpm ... * [ ok ] * Mounting network filesystems ... * [ ok ] * Starting local ... , and in /var/log/message I see: Aug 22 12:36:56 ACM dhcpcd[2435]: dhcpcd-10.0.2 starting Aug 22 12:36:56 ACM dhcpcd[2437]: dev: loaded udev Aug 22 12:36:56 ACM dhcpcd[2437]: DUID 00:01:00:01:20:97:45:37:60:45:cb:9c:5b:d6 Aug 22 12:36:56 ACM dhcpcd[2437]: enp38s0: waiting for carrier Aug 22 12:36:58 ACM kernel: igb 0000:26:00.0 enp38s0: igb: enp38s0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX/TX Aug 22 12:36:59 ACM dhcpcd[2437]: enp38s0: carrier acquired Aug 22 12:36:59 ACM kernel: IPv6: ADDRCONF(NETDEV_CHANGE): enp38s0: link becomes ready Aug 22 12:36:59 ACM dhcpcd[2437]: enp38s0: IAID cb:9c:5b:d6 Aug 22 12:37:00 ACM dhcpcd[2437]: enp38s0: rebinding lease of 192.168.178.86 Aug 22 12:37:00 ACM dhcpcd[2437]: enp38s0: probing address 192.168.178.86/24 Aug 22 12:37:05 ACM dhcpcd[2437]: enp38s0: leased 192.168.178.86 for 864000 seconds Aug 22 12:37:05 ACM dhcpcd[2437]: enp38s0: adding route to 192.168.178.0/24 Aug 22 12:37:05 ACM dhcpcd[2437]: enp38s0: adding default route via 192.168.178.1 .. > > Aug 22 09:24:29 ACM /etc/init.d/net.enp38s0[2695]: The dhcpcd version > > is too old.

I don't understand what I just did, by deleting net.enp38s0, though it appeared to have fixed the problem. That worries me. Could you possibly explain to me a bit more what that removal did?

So, the current state is my machine appears to be working, without error messages on boot-up, but I don't understand why. -- Alan Mackenzie (Nuremberg, Germany).
