I've setup an encrypted UEFI-Booting Arch installation1. Why am I not asked for the phrase on booting?
Remark: If I change the name crypto in `/etc/crypttab` to e.g. encryptedBOOT I am required to enter a password on boot, though I can enter anything and get to login without a hassle.

# 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=(/crypto_keyfile.bin)
# 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 autodetect modconf block keymap encrypt lvm2 resume filesystems keyboard fsck)
# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"
# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()
