#ABOUT#{{{
# 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

# 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.
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 block filesystems)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev block 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 block mdadm encrypt filesystems)
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS=(base udev block lvm2 filesystems)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
