+Assumptions: The server has two identically sized hard drives
+== Installing Debian ==
+
+Ideally - you should boot using a Debian installer that uses the serial
+console. If you can't - just install the normal way.
+
+=== PREPARE YOUR LAPTOP - Screen
+
+ * Install screen on your debian laptop:
+
+{{{
+$ sudo apt-get install screen
+}}}
+
+ * Connect your serial cable (or USB - serial cable) from your laptop to the
+server.
+
+ You may want to check dmesg after plugging in the cable to see which device
+is being used. You should have a line along the lines of:
+
+ usb 3-1: PL-2303 converter now attached to ttyUSB0
+
+ * Start screen with:
+{{{
+mkdir screen-log
+cd screen-log
+screen -L /dev/ttyUSB0 115200
+}}}
+
+=== Install Linux ===
+
+ * Put in Daniel's Serial Console debian installer and boot (note - if you don't have a serial installer, use a normal installer and a keyboard and monitor attached to the server).
+
+ * At the boot prompt hit enter to install the 2.6 kernel
+
+==== INITIAL INSTALL ====
+
+ * [Skipping easy steps]
+
+ * Manually partition the drive
+
+ * There should be two drives. Remove any existing partitions.
+
+ * Add one partition on each disk that is:
+{{{
+# bootable
+# 250 MB
+# Physical volume for RAID array
+}}}
+
+ * Add a second parition on each disk that is:
+{{{
+# Takes up remaining space
+# Physical volume for RAID array
+}}}
+
+ * Choose "Congifure software RAID"
+
+ * Choose "Create MD Device"
+
+ * Choose RAID1
+
+ * Number of active devices: 2
+
+ * Number of spare devices: 0
+
+ * Now select the first partition on each device.
+
+ * Click Continue. Repeat for second partition on each device.
+
+ * When you are done, click Finish. Now you are back at the partition menu.
+
+ * Scroll down to the raid devices. Modify as follows:
+
+{{{
+250 MB RAID device: Filesystem: ext3, mount on /boot
+Remaining: Physical Volume for LVM
+}}}
+
+ * Choose "Congifure LVM"
+
+ * Create a volume group called vg_nameofserver0
+
+ * Create a logical volumes in this volume group
+
+{{{
+dom0: 1 GB
+dom0-swap: 512MB
+}}}
+ * After returning to the main disk config menu, click on the LVM #1 and configure it to use ext3 and /.
+ * Click on the #2 lvm disk and configure it as swap
+
+
+==== AFTER REBOOT ====
+
+ * Set Hardware clock to GMT (even if it isn't)
+
+ * Insert root password into pass db
+
+ * Create new user: mayfirst
+
+ * Do not select any of the pre-set application packages. Just tab to OK.
+
+ * For mail congiration - choose No configuration (we will be installing
+postfix later)
+
+ * Root and postmaster recipient: root@mayfirst.org
+
+==== POST INSTALL ====
+
+ * Setup xen
+
+ * Install with:
+
+{{{
+apt-get install xen-hypervisor-3.0.3-1-i386 xen-linux-system-2.6.18-4-xen-686 libc6-xen
+}}}
+
+ * Edit /boot/grub/menu.1st
+
+{{{
+## Xen hypervisor options to use with the default Xen boot option
+# xenhopt=dom0_mem=131072
+}}}
+
+ * run update-grub and reboot
+
+ * Install bridge-utils and xen-tools
+{{{
+aptitude install bridge-utils xen-tools
+/etc/init.d/xend restart
+}}}
+
+ * Edit /etc/xen-tools/xen-tools.conf.
+
+Apply the following diffs:

+
+ * Login as root and install the following packages:
+
+{{{
+# apt-get install --purge ssh ntpdate ntp-server sudo vim less rsync postfix
+}}}
+
+ * Add the group wheel.
+
+{{{
+# addgroup wheel
+}}}
+
+ * Add mayfirst to wheel:
+
+{{{
+# addgroup mayfirst wheel
+}}}
+
+ * Configure sudo:
+{{{
+# visudo
+}}}
+
+Add a line at the bottom that says:
+{{{
+%wheel  ALL=(ALL) ALL
+}}}
+ * Upload the mayfirst public keys to:
+
+.ssh/authorized_keys
+
+ * Configure ssh to only accept connections with auth keys (unless this is a server that should be accessible by members)
+
+Edit /etc/ssh/sshd_config
+
+Uncomment the last line that says:
+
+{{{
+#UsePAM yes

+
+Uncomment and change the ChallengeResponseAuthentication line to match the following:
+
+{{{
+ChallengeResponseAuthentication no
+}}}
+
+Reload ssh:
+
+{{{
+# /etc/init.d/ssh reload
+}}}
+
+=== SERIAL CONSOLE LOGIN ===
+
+ If you did not use the serial console installer, then perform the following:
+
+ * Edit the /etc/inittab file.
+
+ Uncomment the line that reads:
+
+{{{
+T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100
+}}}
+
+and change 9600 to 115200 so it reads:
+
+{{{
+T0:23:respawn:/sbin/getty -L ttyS0 115200 vt100
+}}}
+
+ * Refresh:
+
+{{{
+$ sudo init q
+}}}
+
+ * Add the following lines after the timeout line in /boot/grub/menu.1st
+
+{{{
+serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
+terminal --timeout=10 serial console
+}}}
+
+ * Add the following lies to the Start Default Options
+You should already have a line such as:
+
+{{{
+# kopt=root=/dev/md0 ro
+}}}
+
+add to it, so that your final line says:
+
+{{{
+# kopt=root=/dev/md0 ro console=ttyS0,115200n8
+}}}
+
+Refresh grub:
+
+{{{
+$ sudo update-grub
+}}}
+
+
+==== Misc ====
+
+ * Uninstall unecesary packages:
+
+{{{
+$ sudo apt-get remove --purge portmap lpr nfs-common ppp
+}}}
+
+ * Make sure no uneeded services are running. Look through /etc/rc2.d. Move
+from S to K any services that are not needed (e.g. rsync and inetd).
+
+=== ENCRYPTED FILE SYSTEM ===
+
+ * Install programs:
+
+{{{
+$ sudo apt-get install dmsetup cryptsetup
+}}}
+
+ * Create an encrypted file system for members:
+
+ * Now, unmount the partition (make sure there is no data on it that you care about).
+
+{{{
+$ sudo umount /home/members
+}}}
+
+ * Create the encrypted filesystem:
+
+{{{
+$ cryptsetup luksFormat /dev/mapper/vg_NAMEOFSERVER0-members
+}}}
+
+You will be prompted for a password. Put password in resource db!
+
+ * Add to crypttab
+
+{{{
+echo crypt_members /dev/mapper/vg_NAMEOFSERVER0-members none luks >> /etc/crypttab
+}}}
+
+ * Start it
+
+{{{
+/etc/init.d/cryptdisks start
+}}}
+
+ * Create a file system on the partition:
+
+{{{
+$ mkfs -t ext3 /dev/mapper/crypt_members
+}}}
+
+ * Remove cryptdisks from the rc2.d directory - we do not want this to start automatically on boot! Instead we want to start it manually so the boot process doesn't hang waiting for a password.
