The Funtoo Linux project has transitioned to "Hobby Mode" and this wiki is now read-only.
Funtoo:New Install Experience/LiveCD page
This tutorial explains Howto build your own LiveCD Funtoo Linux using oficial stage3. After configure the new system using CHROOT, just burn the new ISO file, using the official Área31 Hackerspace tool.
The LiveCD Funtoo Linux, basically a system recovery disk, available as a bootable DVD or USB device to administer or repair your system after an accident. Your goal is to provide an easy way to perform administrative tasks on your computer, such as repairing, creating, and editing your hard disk partitions. It comes with a lot of Open Source software such as system tools (parted, partimage, photorec, foremost, dcfldd, ddrescue, hdparm, and others) and basic tools (editors, browsers, network tools). The LiveCD can be used for both Linux, Mac OS and Windows computers, as well as desktops or servers. This LiveCD does not require installation as it can be booted from a DVD drive or USB device. The kernel supports the most commonly used file systems (ext2 / ext3 / ext4, ReiserFS, Btrfs, XFS, JFS, VFAT, NTFS via ntfs-3g) as well as network file systems (Samba and NFS) encrypted (LUKS).
It is highly recommended to create a new separate partition on your system, to store the /mnt/custom directory data
Mount /mnt/custom directory (optional)ː
root # mkdir -p /mnt/custom ; mount /dev/sdb1 /mnt/custom
Emerge on your host funtoo system tools for cd mastering:
root # emerge cdrtools squashfs-tools isomaster libisoburn mtools
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
Create some directories to mount them as bind, to keep the livecd directory as clean as possible:
root # mkdir -p /mnt/custom/customcd/files/var/cache/portage /mnt/custom/portage-chroot root # mkdir -p /mnt/custom/meta-repo /mnt/custom/customcd/files/var/git root # mount -o bind /mnt/custom/portage-chroot /mnt/custom/customcd/files/var/cache/portage 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
CHROOT
Configure network and use the chroot
root # cp /etc/resolv.conf /mnt/custom/customcd/files/etc/ root # chroot /mnt/custom/customcd/files/ /bin/bash
LiveCD configuration into CHROOT
Update portage tree
root # ego sync
Update world
root # emerge -uDN @world
Configure livecd profile
Remove systemd:
root # epro mix-ins +no-systemd
Configure useflags
root # echo '>=media-libs/gd-2.3.0 fontconfig truetype png jpeg' >> /etc/portage/package.use root # echo 'sys-boot/grub **' >> /etc/portage/package.accept_keywords root # echo 'sys-apps/openrc **' >> /etc/portage/package.accept_keywords root # echo '=sys-apps/openrc-0.41.2-r4' >> /etc/portage/package.mask

Configure fstab
root # echo '# Funtoo LiveCD fstab' > /etc/fstab root # echo 'tmpfs / tmpfs defaults 0 0' >> /etc/fstab
Configure hostname
Edit /etc/conf.d/hostname and insert:
hostname="livecd.funtoo"
Include essential services on boot
root # rc-update add NetworkManager sysinit root # rc-update add autoconfig default root # rc-update add haveged default root # rc-update add sshd default root # rc-update add fixinittab default
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
# ============ 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
# ============ PRINT MESSAGE ===========================
lc1='\e[01;31m' # light red
dc1='\e[00;31m' # dark red
lc2='\e[01;37m' # white
dc2='\e[00;37m' # gray
# fix broken console with utf8 in the alternative-kernels
echo -n -e '\033%G'
kbd_mode -u
LINES=$(stty size|cut -d" " -f1)
fbecho()
{
[ $LINES -ge 28 ] && echo
}
# ============ SHELL PROMPT ============================
exec $SHELL --login
Configure inittab
root # vi /etc/inittab
Change the lines below the comment '# TERMINALS' 'to the following pattern:
root # TERMINALS c1:12345:respawn:/sbin/agetty -nl /bin/bashlogin 38400 tty1 linux c2:12345:respawn:/sbin/agetty -nl /bin/bashlogin 38400 tty2 linux c3:12345:respawn:/sbin/agetty -nl /bin/bashlogin 38400 tty3 linux c4:12345:respawn:/sbin/agetty --noclear 38400 tty4 linux c5:2345:respawn:/sbin/agetty 38400 tty5 linux c6:2345:respawn:/sbin/agetty 38400 tty6 linux
That way we will automatically log in to TTY's from 1 to 3.
