I have a /etc/conf.d/net file which renames my dummy0 interface to dum0: config_dummy0=( "null" ) config_dum0=( "null" ) rename_dummy0="dum0" mac_dum0="00:13:02:2A:A0:40" and I start dum0 as a service by having net.dummy0 in the default runlevel. During system start up, dum0 is setup and started correctly, but I get the following error: * Starting gpm ... [ ok ] * Starting dummy0 * Renaming "dummy0" to "dum0" ... [ ok ] * Stopped configuration of dummy0 due to renaming * Starting dum0 * Changing MAC address of dum0 ... [ ok ] * changed to 00:13:02:2A:A0:40 * Starting ifplugd on dum0 ... [ ok ] * Backgrounding ... * ERROR: cannot start netmount as net.dummy0 could not start After start up, dummy0 is stopped and dum0 is started. Should the interface renaming change propagate in the system start up so that the ERROR is silenced? Reproducible: Always Steps to Reproduce: 1.

We're phasing the renaming of interfaces out of baselayout - use a udev rule instead.
I try to rename the dummy0 interface using udev, be adding in /etc/udev/rules.d/70-persistent-net.rules: # rename dummy0 to dum0 (line 16 is bellow) SUBSYSTEM=="net", KERNEL="dummy0", NAME="dum0" but I get this error when booting: Aug 15 21:18:07 makis udevd[510]: add_to_rules: invalid KERNEL operation Aug 15 21:18:07 makis udevd[510]: add_to_rules: invalid rule /etc/udev/rules.d/70-persistent-net.rules:16' It seems to my that dummy0 does not yet exist, since net.dummy0 has not been started. After net.dummy0 has started. I get from udevinfo udevinfo -a -p /sys/class/net/dummy0 looking at device '/class/net/dummy0': KERNEL=="dummy0" SUBSYSTEM=="net" DRIVER=="" ATTR{weight}=="0" ATTR{tx_queue_len}=="0" ATTR{flags}=="0xa3" ATTR{mtu}=="1500" ATTR{operstate}=="unknown" ATTR{dormant}=="0" ATTR{carrier}=="1" ATTR{broadcast}=="ff:ff:ff:ff:ff:ff" ATTR{address}=="06:de:bc:ba:89:80" ATTR{link_mode}=="0" ATTR{type}=="1" ATTR{features}=="0x0" ATTR{ifindex}=="5" ATTR{iflink}=="5" ATTR{addr_len}=="6" How do I write the renaming rule for dummy0 interface?
Well, it looks correct to me. Assigning to udev.
