Install

Follow Gentoo Linux x86 Handbook.

1. Download gentoo install CD install-x86-minimal-20140415.iso from its website x86 minimal site;

2. Create USB installer: dd bs=4M if=warez/archlinux-2014.04.01-dual.iso of=/dev/sdb && sync;

3. Use this usb key start the laptop;

4. Create a wpa_supplicant conf file:

   $ cat /etc/wpa_supplicant/wpa_supplicant.conf network={ ssid="TP-LINK..." psk="py..." scan_ssid=1 proto=WPA2 }

5. Connect WiFi: /etc/init.d/wpa_supplicant start, verify: ping another host in your wifi network;

6. Test network with ping www.baidu.com, if you can't connect to it, config network:

   ifconfig wlp5s0 down

   ifconfig wlp5s0 192.168.1.103 broadcast 192.168.1.255 netmask 255.255.255.0 up

   route add default gw 192.168.1.253 // get gateway IP with route -n on another host

If you still can't ping a internet website, run dhcpcd wlp5s0 to generate nameservers(stored in /etc/resolv.conf);

1. Partition disk;

2. The command "emerge-webrsync" in step "Configuring Portage" which download Portage snapshot from 163.com is very slow(about 15 minutes);

3. Config kernel manually: make menuconfig: Processor type and features -> Processor family: Core 2/newer Xeon, but there are many errors due to hardware info mismatch. So I give up and use "genkernel" utility to compile the kernel. It takes about 25 minutes;

4. ls /boot/kernel*: /boot/kernel-genkernel-x86-3.12.13-gentoo; ls /boot/initr*: /boot/initramfs-genkernel-x86-3.12.13-gentoo

5. Install vim with emerge vim;

6. emerge sys-boot/grub is slow;

7. After reboot, only loopback nic is detected wiht ifconfig command.

   modprobe wlp5s0

   modprobe: FATAL: Module wlp5s0 not found

   ifconfig wlp5s0 up

   wlp5s0: ERROR while getting interface flags: No such device

   dmesg | grep iwlwifi

   ... request for firmware file 'iwlwifi-1000-5.ucode' failed. ...

   genkernel --menuconfig all

   emerge -v iwlwifi-1000-5.ucode
