1. create a disk

16G seems not enough, go for 32G

$ qemu-img create -f qcow2 install-amd64-minimal-20231015T161657Z.qcow2 32G
Formatting 'install-amd64-minimal-20231015T161657Z.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off compression_type=zlib size=17179869184 lazy_refcounts=off refcount_bits=16

2. Simulate with

skip -enable-kvm

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
$ qemu-system-x86_64 -m 4G -boot order=d \
-cdrom ./install-amd64-minimal-20231015T161657Z.iso \
./install-amd64-minimal-20231015T161657Z.qcow2

3. in qemu simulation

• ip ad

  • ping -c 3 google.com

• gdisk /dev/sda

  • /dev/sda1 as EFI, mkfs.vfat -F 32 /dev/sda1
  • /dev/sda2 as ext4, mkfs.ext4 /dev/sda2

• mount /dev/sda1 to /mnt/gentoo ( /mnt/gentoo already exits)

• date to see if it is OK

  • if not chronyd -q
  • if network is not accessible
    • date 100313162021 set to October 3rd, 13:16 in the year 2021

• choose stage 3 tarball

  • cd /mnt/gentoo && wget https://distfiles.gentoo.org/releases/amd64/autobuilds/20231015T161657Z/stage3-amd64-systemd-20231015T161657Z.tar.xz

• Unpacking the stage tarball

  • tar xpvf stage3-*.tar.xz --xattrs-include='*.*' --numeric-owner

 --xattrs-include='*.*': This option instructs tar to include extended file attributes (xattrs) in the extraction process. Extended file attributes can store additional metadata about files, such as SELinux security context or file capabilities. The argument '*.*' is a pattern that includes all files and directories when extracting xattrs. This ensures that any extended file attributes associated with the files are preserved.

--numeric-owner: This option tells tar to preserve the numeric ownership (user and group IDs) of the files and directories being extracted. It's essential in order to maintain the ownership and permissions of files when extracting the tarball, as it ensures that the original user and group IDs are retained.

4. Configuring compile options

• nano /mnt/gentoo/etc/portage/make.conf
  • add MAKEOPTS="-j4 -l4", --> -l responsive

5. Gentoo ebuild repository

   • mkdir --parents /mnt/gentoo/etc/portage/repos.conf
   • cp -v /mnt/gentoo/usr/share/portage/config/repos.conf /mnt/gentoo/etc/portage/repos.conf/gentoo.conf

6. edity DNS info

• ` nano /mnt/gentoo/etc/resolv.conf as

nameserver 8.8.8.8
nameserver 8.8.4.4

7. arch-chroot /mnt/gentoo /bin/bash

• source /etc/profile
• add this line to /etc/profile

export PS1="(chroot) $PS1"

• source /etc/profile again the prompt will be (chroot) livecd

8. nano /etc/locale.gen

• uncomment en_US.UTF-8 UTF-8 ja_JP.UTF-8 UTF-8
• locale-gen
• add the following lines to the end of /etc/profile`

# 
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

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

• source /etc/profile --> error bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF=8)

8. Configuring Portage

• emerge-webrsync

9. Choosing the right profile

eselect profile list
eselect profile set

10. sync with the @wolrd

emerge --ask --verbose --update --deep --newuse @world
