2015-06-10T13:00:00+01:00 My installation of Ubuntu Mate 15.04 (Vivid) jochum [HOWTO Ubuntu My Installation Crypto root BTRFS lxc]

This is my own documentation of my installation, i assume you have installed Ubuntu Mate 14.10 before.

Grub + cryptoroot + BTRFS works a lot better with Vivid, yeah!


  • Latest Ubuntu Mate
  • Encrypted disk
  • BTRFS root, home and stuff i keep between sys updates.

Install Linux from a livecd

  • Start from the livecd
  • Go to Control Center->Hardware->Keyboard and set the keyboard to german nodeadkeys
  • connect to the internet

Get root and install BTRFS Tools

sudo -s -H
apt-get -y install btrfs-tools

Decrypt the root

cryptsetup --allow-discards luksOpen /dev/sda2 root

Create the root subvolume

mkdir /mnt/btrfs
mount -o subvolid=0,compress=lzo,recovery,noatime /dev/mapper/root /mnt/btrfs
btrfs subvolume create /mnt/btrfs/\@ubuntu_15.04

Mount the new Subvolume to /target

mkdir /target
mount -o subvol=@ubuntu_15.04,compress=lzo,recovery,noatime /dev/mapper/root /target
mkdir -p /target/var/lib/lxc
mkdir -p /target/opt/mono
mkdir -p /target/mnt/btrfs

Rsync /rofs to /target

rsync -avP /rofs /target

Copy stuff from 14.10 to 15.04

cp /etc/mtab /target/etc/

export from='/mnt/btrfs/@ubuntu_14.10'
cp -a $from/etc/hosts /target/etc/
cp -a $from/etc/hostname /target/etc/
cp -a $from/etc/sysctl.conf /target/etc/
cp -a $from/etc/sudoers /target/etc/
cp -a $from/etc/crypttab /target/etc/
cp -a $from/etc/fstab /target/etc/
sed -i -e's/@ubuntu_14.10/@ubuntu_15.04/' /target/etc/fstab
cp -a $from/etc/data_luks.key /target/etc/
cp -a $from/etc/initramfs-tools/modules /target/etc/initramfs-tools
cp -a $from/etc/NetworkManager/system-connections/* /etc/NetworkManager/system-connections/
cp -pfra $from/etc/NetworkManager/dnsmasq.d/* /target/etc/NetworkManager/dnsmasq.d/
cp -a $from/etc/samba/smb.conf /target/etc/samba/
rsync -avP $from/etc/libvirt/ /target/etc/libvirt/

Chroot to /target

mount -o bind,rw /dev /target/dev
mount -o bind,rw /proc /target/proc
mount -o bind,rw /sys /target/sys
mount -o bind,rw /dev/pts /target/dev/pts
mount -o bind,rw /run /target/run

chroot /target /bin/bash

rm -f /usr/lib/locale/locale-archive
locale-gen de_AT.UTF-8 en_US.UTF-8 de_AT en_US
update-locale LANG=de_AT.UTF-8
export LANG=de_AT.UTF-8
dpkg-reconfigure keyboard-configuration
dpkg-reconfigure tzdata

Make sure dhclient never updates resolv.conf


cat <<EOF > /etc/dhcp/dhclient-enter-hooks.d/nodnsupdate
  cat /etc/dhcp/dhclient-enter-hooks.d/nodnsupdate # check

Create your user

export TARGET_USERNAME="pcdummy"
adduser --no-create-home ${TARGET_USERNAME}
usermod -a --groups=sudo,cdrom,floppy,audio,dip,video,plugdev ${TARGET_USERNAME}
passwd -l root
usermod -a -G fuse ${TARGET_USERNAME}

Update the fresh install (still in chroot)

sed -i -e's/archive.ubuntu/ch.archive.ubuntu/g' /etc/apt/sources.list
apt-get update && apt-get -yy dist-upgrade

Update grub.

cat <<'EOF' > /etc/default/grub
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="cgroup_enable=memory swapaccount=1 kopt=root=/dev/mapper/root quiet splash"
GRUB_PRELOAD_MODULES="luks cryptodisk gcry_rijndael gcry_sha1"

Create the lxd user and give him some permissions:

sudo useradd -r -d /var/lib/lxd -s /bin/bash lxd # /bin/bash so i can "ssh lxd@localhost"
sudo usermod -a -G lxd pcdummy
# Give lxd 99 uid/gid ranges to map.
for i in {1..99}; do
	sudo usermod --add-subuids ${i}00000-${i}65536 lxd
	sudo usermod --add-subgids ${i}00000-${i}65536 lxd
done # This takes a while
sudo mkdir /var/lib/lxd
sudo chown lxd:lxd /var/lib/lxd
sudo sudo -H -u lxd mkdir -p /var/lib/lxd/.config/lxc/
sudo sudo -H -u lxd sh -c 'cat <<EOF > /var/lib/lxd/.config/lxc/default.conf
lxc.include = /etc/lxc/default.conf
lxc.id_map = u 0 100000 65537
lxc.id_map = g 0 100000 65537

Allow userspace containers to use the network interfaces:

echo 'lxd veth mlabnatbr0 100' | sudo tee -a /etc/lxc/lxc-usernet 1>/dev/null
echo 'lxd veth mlabbr0 100' | sudo tee -a /etc/lxc/lxc-usernet 1>/dev/null

Restart lxc and lxc-net

sudo service lxc stop
sudo service lxc-net restart
sudo service lxc start

For "ssh lxd@localhost"

sudo apt-get -y install openssh-server
sudo mkdir /var/lib/lxd/.ssh/
sudo cp $HOME/.ssh/ /var/lib/lxd/.ssh/authorized_keys
sudo chown -R lxd:lxd /var/lib/lxd/.ssh/
