Creiamo il mount point

# mkdir /mnt/exherbo && mount /dev/sda2 /mnt/exherbo && cd /mnt/exherbo

Scegliamo l' ultimo stages

# wget http://dev.exherbo.org/stages/exherbo-x86_64-pc-linux-gnu-current.tar.xz
# wget http://dev.exherbo.org/stages/sha1sum
# grep exherbo-x86_64-pc-linux-gnu-current.tar.xz sha1sum | sha1sum -c

Estrarre lo stage

# tar xJpf exherbo*xz

Aggiornare l' fstab

# <fs>      <mountpoint>       <type>     <opts>                <dump/pass>
/dev/sda1       none            swap        sw                      0 0 
/dev/sda2       /               ext4        defaults                0 0
/dev/sda3       /home           ext4        defaults                0 2
tmpfs           /tmp            tmpfs       nodev,nosuid,size=2G    0 0
tmpfs           /dev/shm        tmpfs       defaults                0 0

Prima di iniziare copiare i dns dall' host.

# cp /etc/resolv.conf /mnt/exherbo/etc/resolv.conf

IMPORTANTE: Verifica che si usi davvero l'opzione “rbind” per associare il mount di /dev, altrimenti paludis non funzionerà correttamente.

Montiamo!

# mount -o rbind /dev /mnt/exherbo/dev/

# mount -o bind /sys /mnt/exherbo/sys/

# mount -t proc none /mnt/exherbo/proc/

# chroot /mnt/exherbo /bin/bash

# source /etc/profile

Procediamo all' editing di 2 file importanti, bashrc e options.conf; Dal momento in cui scrivo gli unici editors presenti nello stage sono vi, vim ed emacs. Se si vuole procedere con nano bisogna aggiungerlo:

cave sync

cave resolve nano -x

Iniziamo con bashrc

nano -w /etc/bashrc

CFLAGS="-march=amd64 -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
CHOST="x86_64-pc-linux-gnu"
MAKEOPTS="-j3"
i686_pc_linux_gnu_CFLAGS="-march=native -O2 -pipe"
i686_pc_linux_gnu_CXXFLAGS="-march=native -O2 -pipe"
x86_64_pc_linux_gnu_CFLAGS="-march=native -O2 -pipe"
x86_64_pc_linux_gnu_CXXFLAGS="-march=native -O2 -pipe"

Passiamo a options.conf

nano -w /etc/options.conf

### Base ###
*/* build_options: jobs=4 -recommended_tests -dwarf_compress
*/* targets: x86_64-pc-linux-gnu i686-pc-linux-gnu

Modifica successiva:

### Base ###
*/* build_options: jobs=4 -recommended_tests -dwarf_compress
*/* targets: x86_64-pc-linux-gnu i686-pc-linux-gnu
### driver ###
*/* INPUT_DRIVERS: keyboard mause evdev -acecad -vmmouse
*/* VIDEO_DRIVERS: vesa amdgpu -intel -cirrus -vmware -nouveau -nv
*/* VIDEO_CARDS: -* amdgpu
*/* LINGUAS: -* it_IT it
### USE flag ###
*/* bash-completion ncurses openssl zlib consolekit
### Python ###
*/* python_abis: 2.7 3.6
### ECCEZIONI ###
gnome-desktop/gobject-introspection python_abis: -* 3.6

Finito tutto, procedere al sync

# cave sync

Scaricare e scompattare il kernel

# cd /usr/src/

Creare il link simbolico

# ln -sf /usr/src/linux-4.20 /usr/src/linux
# cd linux
# make menuconfig
# make -j3 && make modules_install install

nano -w /etc/options.conf

### Senza systemd ###
*/* providers: -systemd eudev
*/* -systemd
*/* parts: openrc

Installare openrc:

# cave resolve openrc -x
# cave resolve eudev -x

Rimuovere systemd:

# cave uninstall systemd -u '*/*' -x

Re-installa tutto il mondo

# cave resolve world -x -c

Installare grub2:

# cave resolve grub -x

Utile per riconoscere altri sistemi installati nell' Hard Disk è os-prober

# cave resolve os-prober -x

appena finito, inseriamolo il settore di avvio

# grub-install /dev/sda

Creeiamo la configurazione

# grub-mkconfig -o /boot/grub/grub.cfg

Verifica la configurazione di GRUB 2

# nano /boot/grub/grub.cfg

set timeout=10
set default=0
menuentry "Exherbo" {
set root=(hd0,2)
linux /kernel root=/dev/sda2
}

Per generare l' initramfs installare sys-boot/dracut:

# kernel-install add kernel-version /boot/vmlinuz-kernel-version

Per rimuovere la vecchia versione:

# kernel-install remove kernel-version

nano -w /etc/hostname mio-hostname

* sistemare anche gli host di riferimento, altrimenti i propri pacchetti potrebbero non funzionare come si deve.

nano -w /etc/hosts

127.0.0.1    mio-hostname.dominio    mio-hostname    localhost
::1          localhost

• se se ne ha bisogno per l' eventuale firmware della propria scheda wifi, scaricare l' ultimo firmware

cave resolve linux-firmware

• Settare la password di root

 passwd

• `glibc` only: Install any additional locales you might need.

Il locale `en_GB.UTF-8` ed `en_US.UTF-8` sono installati di default.

# localedef -i en_US -f ISO-8859-1 en_US
# localedef -i it_IT -f UTF-8 it_IT.UTF-8

• And change the LANG environment variable if you prefer a different system wide locale than the

default `en_GB.UTF-8`

# echo LANG="en_US.UTF-8" > /etc/env.d/99locale

• Settiamo la zona oraria, esempio Copenhagen,Denmark,Europe

# ln -s /usr/share/zoneinfo/Europe/Copenhagen /etc/localtime

Riavvia

# reboot

• Remove the stage tarball

      The stage tarball is no longer needed and can be safely removed.

• Clean up packages

      The installation images (stages) contain additional tools which are useful for the
      installation process but are not part of the system nor world sets but the stages set.

      You can identify the additional packages using cave show:

          # cave show stages

      If you wish to remove them, you can simply use cave purge:

          # cave purge

      Alternatively, you can add packages you wish to retain to the world set by using the
      update-world command.  As an example, the following adds gdb to the world set.

          # cave update-world sys-devel/gdb

      Or, if you want to add all packages of the stages set to the world set:

          # cave update-world -s stages

• Add a new user for daily use.

      Some useful groups with a brief description:

1. Administrative Groups:

+ adm used for system monitoring tasks (e.g. journalctl)

              + users traditional group for identifying user accounts (versus system/daemon accounts)
              + wheel used to indicate permission to perform certain restricted operations (e.g.  su)

1. Device Access Groups:

+ disk allows access to various disk device nodes

              + usb   allows access to usb device nodes
              + audio allows access to audio device nodes
              + video allows access to video device nodes (for accelerated video)

          # useradd -m -G adm,disk,wheel,cdrom,audio,video,usb,users ${username}
