Kickstart for Ubuntu 14.04
#Generic Kickstart template for Ubuntu
#Platform: x86 and x86-64
# Customized for Server 14.04 minimal vm install
# Usage:
# - Look through config for any changes you want to do. You may want to change
# the initial admin user. Currently username is ubuntu and password is
# ChangeMe. Also may want to change the list of installed packages. Tried to
# keep it as minimal as possible.
# - Place this somewhere that the vm will be able to see. Web server on LAN
# would work best.
# - OPTIONAL: If you are going to make a bunch of these then may want to setup
# a local apt proxy. Install apt-cacher-ng on some system and edit the line
# below.
# - Create a vm with 8gb drive. You can make a larger one but should have 8
# minimum. Also tip for people setting up in vmware the kernel has support
# for VMXNET3 compiled in so you can use it for initial install.
# - Boot up from iso.
# - Hit F4 and choose 'Install a minimal virtual machine'
# - This is required even though we set it below.
# - Press F6 and hit escape so you edit the boot line. Add the following to the
# end before the --. For example if you did include the '--' the end of boot
# line would be:
# ks= --
# - That's it! It will grab an ip via dhcp on eth0 and setup the system.
# Tweaks:
# - Some people would argue I made too many partitions. Feel free to adjust if
# you set things up differently. I highly recommend at least a /var and /home
# to make sure neither of those filling up will halt the whole system.
# - After partitioning with an 8gb volume you'll have about 1gb left in lvm to
# either expand one of the existing vms or to add a new partition. Again my
# suggesting is a second drive for /opt and/or /srv. If you mess up the OS
# you can unmount the second drive and mount it on a new vm that has the OS
# rebuilt on it.
# - The post script adds the noatime,nodev to options. In some circumstances
# you need the access time (most common use is the mail spool to know when
# you last checked for mail). In those instances you may want to change it to
# relatime for home and/or var.
# - The post script will set the default umask from 022 to 027. This means
# files created will not be world-readable. This is good to have for security
# but if you don't want that comment it out.
