Description of problem: When booting with a static IP address configured on kernel command line, the following message is seen: dracut-initqueue[XXX]: RTNETLINK answers: Network is unreachable This is due to having the following code snippet in network-legacy dracut module: -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< -------- 98 do_static() { : 104 elif ! linkup "$netif"; then : 109 ip route get "$ip" | { 110 read a rest 111 if [ "$a" = "local" ]; then 112 warn "Not assigning $ip to interface $netif, cause it is already assigned!" 113 return 1 114 fi 115 return 0 116 } || return 1 : -------- 8< ---------------- 8< ---------------- 8< ---------------- 8< -------- On line 104, a "linkup" is made, but no IP address assigned (that's expected). Then on line 109 a "ip route get <ip>" is made to check if the <ip> is already assigned. Due to not having an IP address yet (which is expected), the "RTNETLINK answers: Network is unreachable" message is printed to stderr, while it should be hidden from the user. Version-Release number of selected component (if applicable): dracut RH7 and RH8 How reproducible: Always Steps to Reproduce: 1. Boot with a static IP address on kernel command line ip=192.168.122.86::192.168.122.1:24:test:enp1s0:none 2. Check the console or journal # journalctl -b | grep RTNET Actual results: Sep 16 17:17:51 vm-rhel8 dracut-initqueue[472]: RTNETLINK answers: Network is unreachable Expected results: Nothing printed Additional info: Suggested fix: 109 ip route get "$ip" 2>/dev/null | {
