Hi,
My test system and build system doesn't have /etc/resolv.conf file
and then a warning is printed which breaks a number of tests in
master and branch-2.10.
Looks like unbound comes with hardcoded root servers list which could
be the fallback in case of no /etc/resolv.conf, so that message would
be an INFO and could be ignored by the testsuite.
What do you think?
Details below.
lib/dns-resolve.c:
74 void
75 dns_resolve_init(bool is_daemon)
76 {
[...]
84 int retval;
85 #ifdef __linux__
86 retval = ub_ctx_resolvconf(ub_ctx__, "/etc/resolv.conf");
87 if (retval != 0) {
>88 VLOG_WARN_RL(&rl, "Failed to read /etc/resolv.conf: %s",
89 ub_strerror(retval));
90 }
91 #endif
