+# MODULES
+# 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=()
+
+# 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.
+HOOKS=(base udev modconf archiso block filesystems)

+# COMPRESSION
+# Use this to compress the initramfs image. By default, gzip compression
