runlevel的几个目录里都没有设置网卡和dhcpcd的启动,我希望每次开机时手动启动网卡。怎么解决呢?如果解决不了的话,由于本人英语不太好,所以请看到的朋友帮忙在英文板块发个帖子问一下,谢谢了。

如果init是openrc,可以将网络相关服务从rc.service中去除,代码:rc-update show可以列出所有启动项;不过,如果配置正确,网络初始化速度并不慢。当然,加快启动速度,systemd是王道。

用的是openrc, rc-update 里没有网卡和dhcpcd的启动项,而且,把dhcpcd这个软件删掉之后,还是会启动dhcp寻找IP。启动速度并不慢,就是启动的时候dhcp会寻找dhcp服务器,所以会导致慢。

我在这儿也发了贴,帮忙看看吧。

你发的英文帖子我看了,抱歉,我E文太差,不过你贴的rc服务中确实没有加载net组件。

我有过dhcp过程缓慢的经历,那是我用busybox建立的initramfs中,在ramfs中启动网络及dhcp时,Busybox comes with a minimalistic DHCP client called udhcpc,udhcpc运行时长时间搜索dhcp服务,系统也停止在这里,但此时实际根文件系统还未加载。

在实际根文件系统中,dhcpcd运行时不会阻止其它进程运行,所以启动dhcp客户不会影响启动过程。

运行dmesg检查下dhcp在什么时候加载的。

配置一下 /etc/conf.d/net:
config_eth0="null"
