如果我将 wicd 添加到defaults运行级别，它总是在启动后要求输入 root 密码。但如果我将其添加到boot运行级别，则没有连接（有线和无线）：

您会看到“权限被拒绝”错误，因为我标记/etc/resolv.conf为不可变。注意最后一行。

这个问题类似于：https://bbs.archlinux.org/viewtopic.php?id=121589，但硬件时钟是正确的，我找不到任何与ntpdatein相关的脚本/etc/wicd/scripts/postconnect/。
有任何想法吗？

dhcpcd并且wpa_supplicant已经从运行级别中删除default：
gentoo ~ # rc-update -v show | grep dhcpcd
dhcpcd |
gentoo ~ # rc-update -v show | grep wpa
wpa_supplicant |
net.eth0被删除：
gentoo ~ # rc-update -v show | grep eth0
net.eth0 |

今天，日志显示“成功”，但wicd无法连接到任何网络：

答案1
您的硬件时钟设置的时区（UTC 或您的本地时区）和您的 Linux 系统配置认为的时区很可能存在不一致。如果它们不同，hwclock则会在系统初始化期间错误地设置系统时钟，稍后当 NTP 守护程序发现您的系统时间与 UTC 相差了您的本地时区的小时数时，它会修复系统时钟。
要检查您的配置是否与硬件时钟的设置不一致，请运行
date; /sbin/hwclock --show
如果显示的时间相隔数小时，则说明您的配置与硬件时钟设置不匹配。我不熟悉 Gentoo 配置的工作原理，但在其他一些 Linux 发行版上，您可以编辑 /etc/sysconfig/clock 并设置UTC=true或UTC=false取决于您的硬件时钟是否设置为 UTC。我认为您的硬件时钟设置为您当地的时区，所以您需要UTC=false.
答案2
问题解决了！罪魁祸首是……hwclock。
正如我上面所说，下面是配置。对于我的时钟：
clock="UTC"
clock_systohc="NO"
clock_hctosys="NO"
clock_args=""
但我有这行（愚蠢的）/etc/local.d/baselayout1.start：
hwclock --hctosys
使用此配置，以下是启动后的日期时间：
gentoo ~ # hwclock
Wed 21 Mar 2012 10:29:57 AM ICT -0.134053 seconds
gentoo ~ # hwclock --utc
Wed 21 Mar 2012 05:30:01 PM ICT -0.928500 seconds
gentoo ~ # date
Wed Mar 21 10:30:03 ICT 2012
gentoo ~ # date --utc
Wed Mar 21 03:30:06 UTC 2012
hwclock和输出date是正确的，hwclock --utc比 晚 7 小时， 比date --utc早 7 小时。
删除此行hwclock --hctosys并/etc/local.d/baselayout1.start更改clock_systohc和clock_hctosys来"YES"解决/etc/conf.d/hwclock问题：
gentoo ~ # hwclock
Wed 21 Mar 2012 03:33:43 AM ICT -0.404693 seconds
gentoo ~ # hwclock --utc
Wed 21 Mar 2012 10:33:46 AM ICT -0.418345 seconds
gentoo ~ # date
Wed Mar 21 10:33:48 ICT 2012
gentoo ~ # date --utc
Wed Mar 21 03:33:54 UTC 2012
