From 1a9c1479044040c64ca6be91835d8cea7004ddff Mon Sep 17 00:00:00 2001 From: zsdc Date: Thu, 30 Dec 2021 00:41:31 +0200 Subject: dhclient: T4121: Fixed resolv.conf generation at early boot stage In case if a CLI configuration is not available, dhclient cannot add nameservers to a `resolv.conf` file, because `vyos-hostsd` requires that an interface be listed in the `set system name-server` option. This commit introduces two changes: * `vyos-hostsd` service will not be started before Cloud-Init fetch all remote data. This is required because all meta-data should be available for Cloud-Init before any of VyOS-related services start since it is used for configuration generation. * the `vyos-hostsd-client` in the `dhclient-script` will be used only if the `vyos-hostsd` is running. In other words - if VyOS services already started, dhclient changes `resolv.conf` using `vyos-hostsd`; in other cases - does this directly. These changes should protect us from problems with DHCP during system boot if DHCP is required by third-party utils. --- src/systemd/vyos-hostsd.service | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/systemd') diff --git a/src/systemd/vyos-hostsd.service b/src/systemd/vyos-hostsd.service index b77335778..4da55f518 100644 --- a/src/systemd/vyos-hostsd.service +++ b/src/systemd/vyos-hostsd.service @@ -7,7 +7,7 @@ DefaultDependencies=no # Seemingly sensible way to say "as early as the system is ready" # All vyos-hostsd needs is read/write mounted root -After=systemd-remount-fs.service +After=systemd-remount-fs.service cloud-init.service [Service] WorkingDirectory=/run/vyos-hostsd -- cgit v1.2.3
