Workaround: Execute the command on the LiveCD

MOUNT-T proc None/mnt/gentoo/proc

Question 2. Cannot boot normally after installation. Grub

Problem 3.config_devtmpfs=yis required in your kernel configuration

The kernel was not selected when it was compiled.

Cannotstart Udev as Udev ud-mount not start is not started by default.

Re-compiling the kernel to find relevant options

Devicedrivers--->

Genericdriver Options--->

(/sbin/hotplug) path to uevent Helper

[*] Maintain a DEVTMPFS filesystem to mount At/dev

[*] AutoMount Devtmpfs At/dev, after the kernel mounted the Rootfs

Question 4. Gentoo installed, can not be networked, but ping address error, check/etc/resolv.conf found no set nameserver, but after setting reboot, Resolv.conf will become the original appearance.

Workaround:/etc/conf.d/net plus one line, "dns_servers_eht0=xxx.xxx.xxx.xxx", normal after reboot.

Question 5. The problem with the graphics card. Compilation is generally not compiled with graphics cards. When using the desktop, compile the install driver.

Nvidiafb:unkonwnna_arch

Try to compile kernel remove nvidiaframebuffer support, I compile the Nvidia and VESA all add, the result is no matter the resolution is not going, DMESG looked, kernel seems to be loaded first Nvidiaframebufer, So I removed the nvidiaframebuffer results. \

I810does No support SMP

Unableto mount Root fs on Unkonwn-block (0,0)

Question 6. Low-level problem there's even a make.conf merge, OK.

!!! Found 2 make.conf files, using both '/etc/make.conf ' and '/etc/portage/make.conf '

Calculatingdependencies ... done!

The default is to find the contents of/etc/portage/make.conf, '/etc/make.conf merged into/etc/portage/make.conf.

Problem Endtarce Do_early_param kernel compilation is problematic.
