How to Customize a NIC Name
如何自定义 NIC 名称
Using a systemd Link File
使用 systemd 链接文件
You can create a systemd https://www.freedesktop.org/software/systemd/man/systemd.link.html[link file] with Ignition configs.
你可以创建一个包含 Ignition 配置的 systemd https://www.freedesktop.org/software/systemd/man/systemd.link.html[链接文件]。
For example, to name NIC with the MAC address `12:34:56:78:9a:bc` to "infra", place a systemd link file at `/etc/systemd/network/25-infra.link` using the xref:producing-ign.adoc[Butane] config snippet shown below:
例如，要将 MAC 地址为 "12:34:56:78:9a:bc "的网卡命名为 "infra"，可使用下图所示的 xref:producing-ign.adoc[Butane] 配置片段在"/etc/systemd/network/25-infra.link "中放置 systemd 链接文件：
Example: Customize NIC via systemd Link File
示例：通过 systemd 链接文件自定义NIC

Using Udev Rules
使用 Udev 规则
Similarly, also through Ignition configs, to name NIC with the MAC address `12:34:56:78:9a:bc` to "infra", create a https://man7.org/linux/man-pages/man7/udev.7.html[udev rule] at `/etc/udev/rules.d/80-ifname.rules` using the xref:producing-ign.adoc[Butane] config snippet shown below:
同样，要通过 Ignition 配置将 MAC 地址为 "12:34:56:78:9a:bc "的网卡命名为 "infra"，请使用下图所示的 xref:producing-ign.adoc[Butane] 配置片段在 `/etc/udev/rules.d/80-ifname.rules` 中创建 https://man7.org/linux/man-pages/man7/udev.7.html[udev规则]：
Example: Customize NIC via Udev Rules
示例：通过 Udev 规则自定义 NIC
variant: fcos
version: {butane-latest-stable-spec}

files:
- path: /etc/udev/rules.d/80-ifname.rules

Networking in the Initramfs via Kernel Arguments
通过内核参数在 Initramfs 中联网
If networking in the initramfs is required, the kernel argument `ifname=` will dynamically create a udev rule to change the name of a NIC.
如果需要在 initramfs 中联网，内核参数 `ifname=` 将动态创建一条 udev 规则来更改网卡名称。
Currently, unlike other parts of the networking config from the initramfs (e.g. static IPs, hostnames, etc.), these udev rules are not persisted into the real root. If the custom name needs to be applied to the real root, either a link file or udev rule must be created, as shown above. See xref:https://github.com/coreos/fedora-coreos-tracker/issues/553[this issue] for more details.
目前，与 initramfs 中网络配置的其他部分（如静态 IP、主机名等）不同，这些 udev 规则不会持久存在实际根目录中。如果需要将自定义名称应用到实际根目录，则必须创建链接文件或 udev 规则，如上所示。详见 xref:https://github.com/coreos/fedora-coreos-tracker/issues/553[这个讨论]。
For example, to give the NIC with the MAC address `12:34:56:78:9a:bc` a name of "infra", provide a `ifname=infra:12:34:56:78:9a:bc` kernel argument. A udev rule would be created in the initramfs like:
例如，要给 MAC 地址为 "12:34:56:78:9a:bc "的网卡命名为 "infra"，需要提供一个 "ifname=infra:12:34:56:78:9a:bc "内核参数。就会在 initramfs 中创建一个类似的 udev 规则：
# cat /etc/udev/rules.d/80-ifname.rules
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="12:34:56:78:9a:bc", ATTR{type}=="1", NAME="infra"
# cat /etc/udev/rules.d/80-ifname.rules
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="12:34:56:78:9a:bc", ATTR{type}=="1", NAME="infra"
