a 1 dollar tip at 15% calculates out to an order of $6.66.

This is the first attempts to declutter area31 and make things more readable, and ditch the extra unneeded hoop jumping while implementing maintainability.

Construction of the environment Funtoo

Get the oficial LiveCD created by Área31 Hackerspace

https://area31.net.br/downloads/iso/funtoo-livecd-area31-5.4.iso

After boot using LiveCD created by Área31 Hackerspace, create and format all partitionsː 

root # mkswap /dev/sda2
root # mkfs.ext4 /dev/sda1

Activate swap and mount /mnt/custom directoryː 

root # swapon /dev/sda2
root # mkdir -p /mnt/custom ; mount /dev/sda1 /mnt/custom

Get and extract stage3 (64bits) from https://www.funtoo.org/Generic_64 ː 

root # wget https://build.funtoo.org/1.4-release-std/x86-64bit/generic_64/stage3-latest.tar.xz -P /mnt/custom
root # mkdir -p /mnt/custom/customcd/files ; tar xpf /mnt/custom/stage3-latest.tar.xz -C /mnt/custom/customcd/files

CHROOT

Configure network and use the chroot

root # cp /etc/resolv.conf /mnt/custom/customcd/files/etc/
root # mkdir -p /mnt/custom/customcd/files/var/cache/portage /mnt/custom/portage-chroot
root # mount -o bind /mnt/custom/portage-chroot /mnt/custom/customcd/files/var/cache/portage
root # mkdir -p /mnt/custom/meta-repo /mnt/custom/customcd/files/var/git
root # mount -o bind /mnt/custom/meta-repo/ /mnt/custom/customcd/files/var/git
root # cd /mnt/custom/customcd/files/ ; mount -o bind /proc/ proc ; mount -o bind /sys sys ; mount -o rbind /dev dev
root # chroot /mnt/custom/customcd/files/ /bin/bash

LiveCD configuration into CHROOT

root # . /etc/profile ; cd ; export PS1="(chroot) $PS1"

Update portage tree

root #  ego sync


Get Area31 overlay

Clone repo: 

root # mkdir -p /etc/portage/localpatches /mnt/funtoo /var/overlay
root # cd /var/overlay ; git clone https://github.com/area31/area31-ebuilds.git
root # mv area31-ebuilds area31-hackerspace

Configure /etc/portage/repos.conf/overlay-area31-hackerspace.conf

[overlay-area31-hackerspace]
location = /var/overlay/area31-hackerspace
auto-sync = no
priority = 10

configure /mnt/funtoo/portage/make.conf

Adjust various services on boot

Just run: 

root # bash /usr/sbin/sysresccd-area31-setservices

Enable Local Patches to Ebuilds: 

root # ln -s /etc/portage/foobashrc.bashrc /etc/portage/bashrc

Compile kernel

Configure ebuild

root # emerge sys-kernel/debian-sources

Configure fstab

Clear fstab: 

root # echo '# Funtoo LiveCD fstab' > /etc/fstab

Configure automatic login [RECOMMENDED]

Make script bashlogin

root # touch /bin/bashlogin ; chmod +x /bin/bashlogin ; vi /bin/bashlogin

With the following content:

   /bin/bashlogin 
#!/bin/sh
cd /root
export LANG=en_US.UTF-8
export HOME=/root
export SHELL=/bin/bash
export PATH=/sbin:/bin:/usr/sbin:/usr/bin
export MAIL=/var/mail/root
export USER=root

source /etc/profile

exec $SHELL --login

Configure inittab

  • automatically log in to all TTY's
root # sed -i "s%sbin/agetty%sbin/agetty -n1 /bin/bashlogin%" /etc/inittab

Configure Time Zone

Configure to UTCː 

root # ln -sf /usr/share/zoneinfo/UTC /etc/localtime

Make automatic post-login banner [OPTIONAL]

Include banner on /etc/bash/bashrc: 

root # echo '/bin/bashlogin-banner' >> /etc/bash/bashrc

Create the script with the following content: 

root # touch /bin/bashlogin-banner ; chmod +x /bin/bashlogin-banner ; vi /bin/bashlogin-banner
root #!/bin/sh
root # ============ ENV VARS ================================
cd /root
export LANG=en_US.UTF-8
export HOME=/root
export SHELL=/bin/bash
export PATH=/sbin:/bin:/usr/sbin:/usr/bin
export MAIL=/var/mail/root
export USER=root

source /etc/profile

root # ============ PRINT MESSAGE ===========================
lc1='\e[01;31m' # light red
dc1='\e[00;94m' # light blue
lc2='\e[01;37m' # white
dc2='\e[00;37m' # gray

root # fix broken console with utf8 in the alternative-kernels
echo -n -e '\033%G'
kbd_mode -u

LINES=$(stty size

Install aditional locales [OPTIONAL]

root # echo 'pt_BR.UTF-8 UTF-8' >> /etc/locale.gen
root # locale-gen

Enable date and time on history

Add these lines on /etc/profile 

export HISTTIMEFORMAT="%h/%d %H:%M:%S "
export HISTFILESIZE="1000000"
export HISTSIZE="1000000"

Exit from CHROOT

root # exit

Prepare the iso environment (Kernel + GRUB)

Download and extract the required files: 

root # cd /mnt/custom/customcd
root # wget https://area31.net.br/downloads/ebuilds/releases/isoroot-livecd-funtoo-area31-5.0.tar.bz2
root # tar xjpf isoroot-livecd-funtoo-area31-5.0.tar.bz2 -C /mnt/custom/customcd


Prepare initram

Make backup: 

root # cd /mnt/custom/customcd
root # tar cpf isoroot-bkp.tar isoroot

Configure initram created by Área31 Hackerspace

Get latest initram from Área31 Hackerspace: 

root # mkdir -p /usr/src/initramfs
root # cd /usr/src/initramfs
root # rm /mnt/custom/customcd/isoroot/isolinux/initram.igz
root # wget https://area31.net.br/downloads/releases/initram-ara31-overlayfs-5.0.igz -O /usr/src/initram.igz

Unpack initram created by Área31 Hackerspace: 

root # cat /usr/src/initram.igz | xz -d | cpio -id

Or unpack initram from LiveCD: 

root # cat /livemnt/boot/isolinux/initram.igz | xz -d | cpio -id

Copy modules from kernel to initram

root # cp -rp /mnt/custom/customcd/files/lib/modules/* lib/modules


Repack initram

root # rm -f /usr/src/initram.igz
root # cd /usr/src/initramfs
root # find . | cpio -H newc -o | xz --check=crc32 --x86 --lzma2 > /usr/src/initram.igz

Copy new initram and kernel to isoroot dir

root # cp /usr/src/initram.igz /mnt/custom/customcd/isoroot/isolinux/initram.igz
root # cp /mnt/custom/customcd/files/boot/kernel-debian-sources* /mnt/custom/customcd/isoroot/isolinux/rescue64
root # mkdir -p /mnt/custom/customcd/isoroot/boot/EFI/BOOT /mnt/custom/customcd/isoroot/efi/boot
root # cp /mnt/custom/customcd/isoroot/efi/bootx64.efi /mnt/custom/customcd/isoroot/boot/EFI/BOOT/bootx64.efi
root # cp /mnt/custom/customcd/isoroot/efi/bootx64.efi /mnt/custom/customcd/isoroot/efi/boot

Remove temporary files and umount /proc, /dev, /sys

root # rm -rf /mnt/custom/customcd/files/usr/src/* /mnt/custom/customcd/files/var/tmp/portage
root # cd / ; umount /mnt/custom/customcd/files/var/cache/portage /mnt/custom/customcd/files/var/git
root # cd /mnt/custom/customcd/files/ ; umount proc sys
root # umount -l dev ; cd

Make iso file

root # sh /usr/share/sysresccd-area31/sysresccd-area31-targets make-iso

Get new iso funtoo

ISOs are always generated in the same directory: 

/mnt/custom/customcd/isofile

Plug in the USB stick

Just make sure the USB stick has been plugged in, and wait a few seconds to be sure the device has been detected by the system.

Execute the installer

Now you just have to execute the installation script which is at the root of the CD-ROM. This script requires several commands to run but it won't be a problem. To be sure the script will always work, these commands are part of the CD-ROM: 

root # cd /tmp/cdrom
root # bash ./usb_inst.sh

Unmount the ISO image

Now you can unmount the ISO image 

root # cd ~
root # umount /tmp/cdrom
