I installed dns/bind916 on my home server and configured it so it worked as both authoritative and recursor. Then I added 'nameserver 127.0.0.1' to /etc/resolv.conf and everything worked fine. But after updating OS from 12.2-RELEASE to 13.0-RELEASE I noticed execution of some rc scripts fails at boot time because of DNS lookup error. And I also found these scripts are executed earlier than 'named'. Now let me use 'ntpdate' as an example. If I run `rcorder /etc/rc.d/* /usr/local/etc/rc.d/*` on 12.2-RELEASE, then I get following result. ---------------------------------------------------------------------- root@rolling-vm-freebsd3[474]# uname -a FreeBSD rolling-vm-freebsd3.home.utahime.org 12.2-RELEASE-p6 FreeBSD 12.2-RELEASE-p6 GENERIC amd64 root@rolling-vm-freebsd3[475]# rcorder /etc/rc.d/* /usr/local/etc/rc.d/* /etc/rc.d/growfs /etc/rc.d/sysctl /etc/rc.d/hostid /etc/rc.d/zvol /etc/rc.d/dumpon (snip) /etc/rc.d/static_arp /etc/rc.d/bridge /etc/rc.d/route6d /etc/rc.d/NETWORKING /etc/rc.d/mountcritremote /etc/rc.d/devfs /etc/rc.d/ipmon /etc/rc.d/kdc /etc/rc.d/mdconfig2 /etc/rc.d/newsyslog /etc/rc.d/syslogd /usr/local/etc/rc.d/tcsd /usr/local/etc/rc.d/named /etc/rc.d/watchdogd /etc/rc.d/savecore /etc/rc.d/archdep /etc/rc.d/linux /etc/rc.d/sysvipc /etc/rc.d/SERVERS /usr/local/etc/rc.d/tpmd /usr/local/etc/rc.d/stunnel /etc/rc.d/accounting /etc/rc.d/ntpdate /etc/rc.d/rpcbind /etc/rc.d/nfsclient /etc/rc.d/nisdomain (snip) ---------------------------------------------------------------------- As you can see, while 'named' is executed before SERVERS, 'ntpdate' is done after it. On the other hand I get following result on 13.0-RELEASE. ---------------------------------------------------------------------- root@rolling-vm-freebsd2[332]# uname -a FreeBSD rolling-vm-freebsd2.home.utahime.org 13.0-RELEASE FreeBSD 13.0-RELEASE #0 releng/13.0-n244733-ea31abc261f: Fri Apr 9 04:24:09 UTC 2021 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64 root@rolling-vm-freebsd2[333]# rcorder /etc/rc.d/* /usr/local/etc/rc.d/* /etc/rc.d/dhclient /etc/rc.d/dumpon /etc/rc.d/growfs /etc/rc.d/natd (snip) /etc/rc.d/netwait /etc/rc.d/blacklistd /etc/rc.d/local_unbound /etc/rc.d/NETWORKING /etc/rc.d/pppoed /etc/rc.d/kdc /etc/rc.d/kfd /etc/rc.d/nfsuserd /etc/rc.d/iscsid /etc/rc.d/ipropd_slave /etc/rc.d/nfscbd /etc/rc.d/iscsictl /etc/rc.d/ipropd_master /etc/rc.d/kadmind /etc/rc.d/kpasswdd /etc/rc.d/mountcritremote /etc/rc.d/wpa_supplicant /etc/rc.d/motd /etc/rc.d/accounting /etc/rc.d/cleartmp /etc/rc.d/dmesg /etc/rc.d/archdep /etc/rc.d/gptboot /etc/rc.d/hostapd /etc/rc.d/virecover /etc/rc.d/mdconfig2 /etc/rc.d/devfs /etc/rc.d/os-release /etc/rc.d/newsyslog /etc/rc.d/linux /etc/rc.d/syslogd /etc/rc.d/sysvipc /etc/rc.d/watchdogd /etc/rc.d/savecore /etc/rc.d/ntpdate /etc/rc.d/localpkg /etc/rc.d/auditd /etc/rc.d/bsnmpd /etc/rc.d/pwcheck /etc/rc.d/power_profile /etc/rc.d/rpcbind /etc/rc.d/auditdistd /usr/local/etc/rc.d/named /etc/rc.d/nfsclient /etc/rc.d/hastd /etc/rc.d/SERVERS /etc/rc.d/nisdomain /usr/local/etc/rc.d/stunnel /usr/local/etc/rc.d/tpmd /usr/local/etc/rc.d/tcsd (snip) ---------------------------------------------------------------------- Now both 'named' and 'ntpdate' are executed before SERVERS. And unfortunately the latter is earlier than the former. So it is natural that execution of 'ntpdate' fails with DNS lookup failure. I compared ntpdate rc script between releng/12.2 and releng/13.0 but there is no difference. ---------------------------------------------------------------------- yasu@rolling-vm-freebsd2[1035]% pwd /usr/src yasu@rolling-vm-freebsd2[1036]% git diff origin/releng/12.2 origin/releng/13.0 -- libexec/rc/rc.d/ntpdate yasu@rolling-vm-freebsd2[1037]% ---------------------------------------------------------------------- And of cource there is no difference with /usr/local/etc/rc.d/named either. So it seems evaluation of rcorder(8) is changed between 12.2-RELASE and 13.0-RELEASE. Then is there any way to make 'named' rc script invoked earlier at boot time on 13.0-RELEASE?
