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).

   Warning

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 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

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"

Configure livecd profile

Remove systemd:

root # epro mix-ins +no-systemd
