Przewodnik Instalacji: 'chroot' do nowego systemu
Żeby zainstalować Funtoo, najpierw używamy chroot. Polecenie "przełącza" na nowy system Funtoo Linux. Wpisywane odtąd komendy będą uruchomiać się na nowo rozpakowanym systemie.
Przed 'chroot'owaniem, należy wykonać kilka czynności aby skonfigurować środowisko 'chroot'. Trzeba będzie zamontować /proc, /sys oraz /dev wewnątrz nowego systemu. Aby to zrobić, użyj następujących poleceń:
root # cd /mnt/funtoo root # mount -t proc none proc root # mount --rbind /sys sys root # mount --rbind /dev dev
Aby mieć prawidłowe nazwy hostów internetowych (DNS) w środowisku 'chroot', kopiujemy plik resolv.conf :
root # cp /etc/resolv.conf /mnt/funtoo/etc/
Teraz możesz 'chroot'ować do nowego systemu. Użyj polecenia env przed poleceniem chroot aby upewnić się, że żadne z ustawień środowiska instalacyjnego nie zostaną przeniesione do nowego systemu:
root # chroot . /bin/su --login chroot #
This chroot command, above, executes /bin/su --login inside the new environment. According to the su man page, su with the --login option provides "an environment similar to what the user would expect had the user logged in directly." That is what we want, as it will prevent any existing environment variables on the LiveCD from being set inside the chroot.
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.
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 your live CD.
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:
chroot # export PS1="(chroot) $PS1"
Test internet name resolution from within the chroot:
chroot # ping -c 5 google.com
If you can't ping, make sure that /etc/resolv.conf specifies a valid IP address for a reachable nameserver in its nameserver setting.
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.
