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 root # mkdir -p /mnt/custom/customcd/files/mnt/funtoo
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 # rm -rf /mnt/custom/customcd/files/usr/src ; mkdir -p /mnt/custom/kernel-usr-src /mnt/custom/customcd/files/usr/src 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 # mount -o bind /mnt/custom/kernel-usr-src /mnt/custom/customcd/files/usr/src root # cd /mnt/custom/customcd/files/ ; mount -o bind /proc/ proc ; mount -o bind /sys sys ; mount -o rbind /dev dev
Into 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"
Set root password and permit login using SSH
root # echo -e "root\nroot" | passwd root root # echo 'PermitRootLogin yes' >> /etc/ssh/sshd_config
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
Install script bashlogin
root # emerge sys-apps/livecd-funtoo-scripts
Configure inittab
root # vi /etc/inittab
Change the lines below the comment '# TERMINALS' 'to the following pattern:
/etc/inittab # TERMINALS
c1:12345:respawn:/sbin/agetty -nl /usr/bin/bashlogin 38400 tty1 linux
c2:12345:respawn:/sbin/agetty -nl /usr/bin/bashlogin 38400 tty2 linux
c3:12345:respawn:/sbin/agetty -nl /usr/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.
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 '/usr/bin/bashlogin-banner' >> /etc/bash/bashrc
Use VIM instead VI
root # eselect vi set vim
Install aditional locales [OPTIONAL]
root # echo 'pt_BR.UTF-8 UTF-8' >> /etc/locale.gen root # locale-gen
Exit from CHROOT
root # exit
Out of CHROOT
