周末安装了OracleLinux 9.2的系统，配置网卡时发现/etc/sysconfig/network-scripts/目录下也不存在网卡信息了，只有一个说明文件，readme-ifcfg-rh.txt

网卡配置信息都在/etc/NetworkManager/system-connections/目录下了

[root@db network-scripts]#  more readme-ifcfg-rh.txt
NetworkManager stores new network profiles in keyfile format in the
/etc/NetworkManager/system-connections/ directory.

Previously, NetworkManager stored network profiles in ifcfg format
in this directory (/etc/sysconfig/network-scripts/). However, the ifcfg
format is deprecated. By default, NetworkManager no longer creates
new profiles in this format.

Connection profiles in keyfile format have many benefits. For example,
this format is INI file-based and can easily be parsed and generated.

Each section in NetworkManager keyfiles corresponds to a NetworkManager
setting name as described in the nm-settings(5) and nm-settings-keyfile(5)
man pages. Each key-value-pair in a section is one of the properties
listed in the settings specification of the man page.

If you still use network profiles in ifcfg format, consider migrating
them to keyfile format. To migrate all profiles at once, enter:

# nmcli connection migrate

This command migrates all profiles from ifcfg format to keyfile
format and stores them in /etc/NetworkManager/system-connections/.

Alternatively, to migrate only a specific profile, enter:

# nmcli connection migrate <profile_name|UUID|D-Bus_path>

For further details, see:
* nm-settings-keyfile(5)
* nmcli(1)
