# This script will set up an Arch installation with a 100 MB /boot partition
# and an encrypted LVM partition with swap and / inside.  It also installs
# and configures systemd as the init system (removing sysvinit).
#
# You should read through this script before running it in case you want to
# make any modifications, in particular, the variables just below, and the
# following functions:
#
#    partition_drive - Customize to change partition sizes (/boot vs LVM)
#    setup_lvm - Customize for partitions inside LVM
#    install_packages - Customize packages installed in base system
#                       (desktop environment, etc.)
#    install_aur_packages - More packages after packer (AUR helper) is
#                           installed
#    set_netcfg - Preload netcfg profiles

# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES="ext4 $vid"

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
# Some users may wish to include modprobe.conf for custom module options
# like so:
#    FILES="/etc/modprobe.d/modprobe.conf"
FILES=""

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS="base"
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS="base udev autodetect pata scsi sata filesystems"
#
##   This is identical to the above, except the old ide subsystem is
##   used for IDE devices instead of the new pata subsystem.
#    HOOKS="base udev autodetect ide scsi sata filesystems"
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS="base udev pata scsi sata usb filesystems"
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS="base udev pata mdadm encrypt filesystems"
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev usb lvm2 filesystems"
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block keymap keyboard $encrypt lvm2 resume filesystems fsck"

# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.

# This command is executed after a succesful login.
# you can place the %session and %theme variables
# to handle launching of specific commands in .xinitrc
# depending of chosen session and slim theme
#
# NOTE: if your system does not have bash you need
# to adjust the command according to your preferred shell,
# i.e. for freebsd use:
# login_cmd           exec /bin/sh - ~/.xinitrc %session
# login_cmd           exec /bin/bash -login ~/.xinitrc %session
login_cmd           exec /bin/zsh -l ~/.xinitrc %session

# Commands executed when starting and exiting a session.
# They can be used for registering a X11 session with
# sessreg. You can use the %user variable
#
# sessionstart_cmd	some command
# sessionstop_cmd	some command

# Start in daemon mode. Valid values: yes | no
# Note that this can be overriden by the command line
# options "-d" and "-nodaemon"
# daemon	yes

# Available sessions (first one is the default).
# The current chosen session name is replaced in the login_cmd
# above, so your login command can handle different sessions.
# see the xinitrc.sample file shipped with slim sources
