+# Setting up Tools and Environment
+
+    - Install [RVM](https://rvm.io/rvm/install)
+    - Setup paths:
+          export PATH=~/.rvm/bin:$PATH
+    - Install Ruby 1.9.3, if it installed some other version:
+          rvm install 1.9.3
+
+All the dependencies will be fetched automatically.
+
+Vagrant: https://github.com/chipchilders/vagrant.git
+
+To save some time if you've downloaded iso of your distro, put the isos in:
+tools/appliance/iso/
+
+Note, gem may require gcc-4.2, make sure link exists:
+
+    sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2
+
+# How to build SystemVM template appliance
+
+List available appliances one can build:
+
+    veewee vbox list
+
+Modify scripts in definitions/systemvmtemplate/ as per needs.
+Build systemvm template appliance:
+
+    veewee vbox build 'systemvmtemplate'
+
+Start the box:
+
+    veewee vbox up 'systemvmtemplate'

+# - multi:  separate /home, /usr, /var, and /tmp partitions
+d-i partman-auto/choose_recipe select atomic
+d-i partman/default_filesystem string ext3

+# Or provide a recipe of your own...
+# The recipe format is documented in the file devel/partman-auto-recipe.txt.
+# If you have a way to get a recipe file into the d-i environment, you can
+# just point at it.
+#d-i partman-auto/expert_recipe_file string /hd-media/recipe
+
+# If not, you can put an entire recipe into the preconfiguration file in one
+# (logical) line. This example creates a small /boot partition, suitable

+# or encrypted using an MD5 hash.
+#d-i passwd/user-password-crypted password [MD5 hash]
+# Create the first user with the specified UID instead of the default.
+#d-i passwd/user-uid string 1010
+d-i user-setup/encrypt-home boolean false
+d-i user-setup/allow-password-weak boolean true
+
+# The user account will be added to some standard initial groups. To
+# override that, use this.
+d-i passwd/user-default-groups string audio cdrom video admin
+
+### Apt setup
+# You can choose to install non-free and contrib software.
+#d-i apt-setup/non-free boolean true
+#d-i apt-setup/contrib boolean true
+# Uncomment this if you don't want to use a network mirror.
+#d-i apt-setup/use_mirror boolean false
+# Select which update services to use; define the mirrors to be used.
+# Values shown below are the normal defaults.
+#d-i apt-setup/services-select multiselect security, volatile
+#d-i apt-setup/security_host string security.debian.org
+#d-i apt-setup/volatile_host string volatile.debian.org
+
+
+# By default the installer requires that repositories be authenticated
+# using a known gpg key. This setting can be used to disable that
+# authentication. Warning: Insecure, not recommended.
+#d-i debian-installer/allow_unauthenticated string true
+
+### Package selection
+tasksel tasksel/first multiselect standard
+# If the desktop task is selected, install the kde and xfce desktops
+# instead of the default gnome desktop.
+#tasksel tasksel/desktop multiselect kde, xfce
+
+# Individual additional packages to install
+d-i pkgsel/include string openssh-server ntp acpid  sudo bzip2
+
+# Whether to upgrade packages after debootstrap.
+# Allowed values: none, safe-upgrade, full-upgrade
+d-i pkgsel/upgrade select none
+
+# Some versions of the installer can report back on what software you have
+# installed, and what software you use. The default is not to report back,
+# but sending reports helps the project determine what software is most
+# popular and include it on CDs.
+popularity-contest popularity-contest/participate boolean false
+
+### Boot loader installation
+# Grub is the default boot loader (for x86). If you want lilo installed
+# instead, uncomment this:
+#d-i grub-installer/skip boolean true
+# To also skip installing lilo, and install no bootloader, uncomment this
+# too:
+#d-i lilo-installer/skip boolean true
+
+# This is fairly safe to set, it makes grub install automatically to the MBR
+# if no other operating system is detected on the machine.
+d-i grub-installer/only_debian boolean true
+
+# This one makes grub-installer install to the MBR if it also finds some other
+# OS, which is less safe as it might not be able to boot that other OS.
+d-i grub-installer/with_other_os boolean true
+
+# Alternatively, if you want to install to a location other than the mbr,
+# uncomment and edit these lines:
+#d-i grub-installer/only_debian boolean false
+#d-i grub-installer/with_other_os boolean false
+#d-i grub-installer/bootdev  string (hd0,0)
+# To install grub to multiple disks:
+#d-i grub-installer/bootdev  string (hd0,0) (hd1,0) (hd2,0)
+
+# Optional password for grub, either in clear text
+#d-i grub-installer/password password r00tme
+#d-i grub-installer/password-again password r00tme
+# or encrypted using an MD5 hash, see grub-md5-crypt(8).
+#d-i grub-installer/password-crypted password [MD5 hash]
+
+### Finishing up the installation
+# During installations from serial console, the regular virtual consoles
+# (VT1-VT6) are normally disabled in /etc/inittab. Uncomment the next
+# line to prevent this.
+#d-i finish-install/keep-consoles boolean true
+
+# Avoid that last message about the install being complete.
+d-i finish-install/reboot_in_progress note
+
+# This will prevent the installer from ejecting the CD during the reboot,
+# which is useful in some situations.
+#d-i cdrom-detect/eject boolean false
+
+# This is how to make the installer shutdown when finished, but not
+# reboot into the installed system.
+#d-i debian-installer/exit/halt boolean true
+# This will power off the machine instead of just halting it.
+#d-i debian-installer/exit/poweroff boolean true
+
+### Preseeding other packages
+# Depending on what software you choose to install, or if things go wrong
+# during the installation process, it's possible that other questions may
+# be asked. You can preseed those too, of course. To get a list of every
+# possible question that could be asked during an install, do an
+# installation, and then run these commands:
+#   debconf-get-selections --installer > file
+#   debconf-get-selections >> file
+
+
+#### Advanced options
+### Running custom commands during the installation
+# d-i preseeding is inherently not secure. Nothing in the installer checks
+# for attempts at buffer overflows or other exploits of the values of a
+# preconfiguration file like this one. Only use preconfiguration files from
+# trusted locations! To drive that home, and because it's generally useful,
+# here's a way to run any shell command you'd like inside the installer,
+# automatically.
+
+# This first command is run as early as possible, just after
+# preseeding is read.
+# Prevent packaged version of VirtualBox Guest Additions being installed:
+d-i preseed/early_command string sed -i \
+  '/in-target/idiscover(){/sbin/discover|grep -v VirtualBox;}' \
+  /usr/lib/pre-pkgsel.d/20install-hwpackages
+
+# This command is run just before the install finishes, but when there is
+# still a usable /target directory. You can chroot to /target and use it
+# directly, or use the apt-install and in-target commands to easily install
+# packages and run commands in the target system.
