Install Guide, Chapter 9

Para instalar o Funtoo Linux, o comando chroot deve ser utilizado primeiro . O comando chroot "mudará para dentro" do ambiente do sistema Funtoo Linux que será instalado. Deste modo, todos os comandos que você executar após executar o "chroot" serão executados dentro do seu recém extraído sistema Funtoo Linux.

Antes do chroot, existem algumas coisas que precisam ser feitas para ajustar o ambiente chroot. Você precisa montar os sistemas virtuais /proc, /sys e /dev dentro do seu novo ambiente. Use os seguintes comandos para fazer isso:

root # cd /mnt/funtoo
root # mount -t proc none proc
root # mount --rbind /sys sys
root # mount --rbind /dev dev

You'll also want to copy over resolv.conf in order to have proper resolution of Internet hostnames from inside the chroot:

root # cp /etc/resolv.conf /mnt/funtoo/etc/

Now you can chroot into your new system. Use env before chroot to ensure that no environment settings from the installation media are pulled in to your new system:

root # env -i HOME=/root TERM=$TERM /bin/chroot . bash -l

   Note

For users of live CDs with 64-bit kernels installing 32-bit systems: Some software may use uname -r to check whether the system is 32 or 64-bit. You may want to append linux32 to the chroot command as a workaround, but it's generally not needed.

   Important

If you receive the error "chroot: failed to run command `/bin/bash': Exec format error", it is most likely because you are running a 32-bit kernel and trying to execute 64-bit code. Make sure that you have selected the proper type of kernel when booting SystemRescueCD.

It's also a good idea to change the default command prompt while inside the chroot. This will avoid confusion if you have to change terminals. Use this command:

root # export PS1="(chroot) $PS1"

Test internet name resolution from within the chroot:

root # ping -c 5 google.com

If you can't ping, make sure /etc/resolv.conf doesn't contain things like 127.0.x.x addresses, if it does, change the 127.0.x.x entry to 8.8.8.8 -- Google's public dns address. Make sure to replace this with your dns of choice once the system is installed.

Congratulations! You are now chrooted inside a Funtoo Linux system. Now it's time to get Funtoo Linux properly configured so that Funtoo Linux will start successfully, without any manual assistance, when your system is restarted.
