This is an odd request, but my system is booting up too quickly. This triggers a race condition: after my wifi module is loaded, it takes udev about 2.5 seconds to rename the interface to the name I defined in /etc/udev/rules.d/76-net-name-use-custom.rules: [ 5.361370] ath10k_pci 0000:70:00.0: enabling device (0000 -> 0002) [ 7.823223] ath10k_pci 0000:70:00.0 wifi: renamed from wlan0 Sadly, openrc takes less than 2 seconds to go through the "boot" runlevel and then a few more milliseconds to process the "default" runlevel, which includes libvirtd. Since net.lo is not enough to satisfy the net dependency for some reason (even though I explicitly set rc_depend_strict="NO"), the next available net interface is being started instead: net.wifi. At that point in time, it's not available though, failing badly: * Executing: /lib64/rc/sh/openrc-run.sh /lib64/rc/sh/openrc-run.sh /etc/init.d/net.wifi start * Bringing up interface wifi * Skipping module apipa due to missing program: /sbin/arping /bin/arping * Skipping module arping due to missing program: /sbin/arping /bin/arping /usr/sbin/arping /usr/sbin/arping2 * Skipping module br2684ctl due to missing program: br2684ctl * Skipping module clip due to missing program: /usr/sbin/atmsigd * Skipping module netplugd due to missing program: /sbin/netplugd * Skipping module ifplugd due to missing program: /usr/sbin/ifplugd * Skipping module ipppd due to missing program: /usr/sbin/ipppd * Skipping module firewalld due to missing program: firewall-cmd * Skipping module pump due to missing program: /sbin/pump * Skipping module dhcpcd due to missing program: dhcpcd * Loaded modules: adsl bonding l2tp tuntap bridge ccwgroup ethtool dummy hsr macvlan macchanger macnet wpa_supplicant ssidnet iproute2 pppd system vlan dhclient ip6rd ip6to4 * ip link set dev wifi up * ERROR: interface wifi does not exist * Ensure that you have loaded the correct kernel module for your hardware * ERROR: net.wifi failed to start * ERROR: cannot start libvirtd as net.wifi would not start * Executing: /lib64/rc/sh/openrc-run.sh /lib64/rc/sh/openrc-run.sh /etc/init.d/xdm-setup start * ERROR: cannot start netmount as net.wifi would not start Note that normally openrc would try to also start my other interface through net.ether, but I explicitly prohibited hotplugging it, to not block the boot process for two minutes due to an DHCP timeout: rc_hotplug="pcscd net.wifi !net.ether" To counter this race condition, I've also tried having net.* to depend upon udev-settle, hoping that this would block long enough until all events (especially rename events...) have been processed via: rc_net_wifi_need="udev-settle" rc_net_ether_need="udev-settle" but still no dice: * Executing: /lib64/rc/sh/openrc-run.sh /lib64/rc/sh/openrc-run.sh /etc/init.d/virtlogd start * Starting virtlogd ... * start-stop-daemon: fopen `/var/run/virtlogd.pid': No such file or directory * Detaching to start `/usr/sbin/virtlogd' ...

Using a patch like that to trigger a short timeouted loop is allowing enough time to pass so that the device becomes available. Note that I explicitly do not upload it as an attachment to not encourage applying it, since it feels more like an ugly hack than a real solution to the problem: --- /etc/init.d/net.lo.bak 2017-03-20 03:20:31.376968301 +0100 +++ /etc/init.d/net.lo 2017-04-09 11:26:10.205556961 +0200 @@ -604,20 +604,34 @@ start() eoutdent fi - _up 2>/dev/null - - for module in ${MODULES}; do - if [ "$(command -v "${module}_pre_start")" = "${module}_pre_start" ]; then - ${module}_pre_start || exit $? + local exists_timeout="3" found_dev="0" + while [ "${exists_timeout}" -ne "0" ]; do + if ! _exists; then + ewarn "WARNING: interface ${IFACE} did not turn up yet, waiting for it ..." + sleep 1 + else + found_dev="1" + break fi + + exists_timeout="$((exists_timeout - 1))" done - if ! _exists; then + if [ "${found_dev}" -ne "1" ]; then + eerror "ERROR: timeout while waiting for interface ${IFACE}" eerror "ERROR: interface ${IFACE} does not exist" eerror "Ensure that you have loaded the correct kernel module for your hardware" return 1 fi + _up 2>/dev/null + + for module in ${MODULES}; do + if [ "$(command -v "${module}_pre_start")" = "${module}_pre_start" ]; then + ${module}_pre_start || exit $? + fi + done + if ! _wait_for_carrier; then if service_started devd; then ewarn "no carrier, but devd will start us when we have one" Result: * Executing: /lib64/rc/sh/openrc-run.sh /lib64/rc/sh/openrc-run.sh /etc/init.d/virtlogd start * Starting virtlogd ... * start-stop-daemon: fopen `/var/run/virtlogd.pid': No such file or directory * Detaching to start `/usr/sbin/virtlogd' ...

Hopefully the maintainer has got a better idea.
@netifrc maintainers: Is this an OpenRC or netifrc issue? What are your thoughts about it? Thanks, William
