====== Update ======
The below method doesn't work anymore.\\
SSH is inaccessible/unsetable on the iso (2014-09)\\

====== Introduction ======
Purpose: test if it's easily installable, using ZFS avoiding SystemD :-X\\
Main web site: [[https://www.archbsd.net/]]\\
Wiki: [[https://wiki.archbsd.net/index.php/Main_Page]]

====== VM creation ======
From VIrtualBOX: New / BSD / FreeBSD 64\\
RAM: 1024MB\\
Edit the VM for:
  * bidirectional clipboard
  * Bridged Adapter
  * Remove IDE disk
  * Add SATA controller
  * Add SATA disk ~ 5GB
  * Set as SSD hard drive
  * Mount ArchBSD iso in CD
Save and launch the VM
====== Install ======
===== SSH access =====
==== Network ====
Find the ip of your VM:
<code bash>
ifconfig
dhclient em0
</code>
==== Root Password ====
Change root password
<code bash>
passwd</code>
==== SSHD config ====
Setup sshd
<code bash>vi /etc/ssh/sshd_config</code>
Then change/uncomment
<code>
[…]
PermitRootLogin yes
[…]
PasswordAuthentication yes
[…]
ChallengeResponseAuthentication no
</code>
==== Start SSHD ====
Then Launch sshd:
<code bash>
/etc/init.d/sshd start
</code>
\\
Then remote connect to it
===== Setup keyboard =====
<code bash>kbdmap</code>
===== GPT partition =====
<code bash>
gpart create -s gpt ada0
gpart add -s 128k -t freebsd-boot ada0
gpart add -s 1g -t freebsd-swap ada0
gpart add -t freebsd-zfs ada0
</code>
===== ZFS Pool =====
<code bash>
zpool create tank /dev/ada0p3
</code>
Interesting output:
<code>
cannot mount '/tank': failed to create mountpoint
Exit 1</code>
===== Bootloader =====
<code bash>gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i1 ada0</code>
===== ZFS Pool =====
==== Reimport ====
<code bash>mdmfs -t swap -s 128m md /boot/zfs</code>
Interesting output:
<code>mdmfs: mdconfig (attach) exited with error code 1
Exit 1</code>
<code bash>zpool export tank</code>
<code bash>zpool import -o altroot=/mnt -o cachefile=/boot/zfs/zpool.cache -f tank</code>
Interesting output:
<code>cannot mount '/mnt/tank': failed to create mountpoint
Exit 1</code>
==== Checksum (optional) ====
<code bash>zfs set checksum=fletcher4 tank</code>
==== Datasets ====
<code bash>
zfs create -o canmount=off -o mountpoint=legacy tank/ROOT
zfs create -o canmount=on -o compression=on -o mountpoint=/ tank/ROOT/archbsd-0
zfs create -o compression=on -o mountpoint=/home tank/HOME
zfs create -o compression=off -o mountpoint=/root tank/HOME/root
</code>
====== Installing Base ======
<code base>pacstrap /mnt base</code>

Interesting output ...
<code>
downloading required keys...
:: Import PGP key 2048R/, "Claudiu Traistaru <claudiu2004@gmail.com>", created: 2013-09-11? [Y/n] 
error: key "Claudiu Traistaru <claudiu2004@gmail.com>" could not be imported
error: required key missing from keyring
error: failed to commit transaction (unexpected error)
Errors occurred, no packages were upgraded.
==> ERROR: Failed to install packages to new root
Exit 1
</code>

FIXME Workaround:
<code bash>cp /etc/pacman.conf /tmp/. </code>
modifiy /etc/pacman.conf like:
<code>
#SigLevel    = Required DatabaseOptional
SigLevel = Never
</code>

then re-run pacstrap as:
<code base>pacstrap -C /tmp/pacman.conf /mnt base</code>

Errors / warnings:
<code>
