# update_initramfs

# this should be invoked as late as possible for any modifications by
# customize_image (userpatches) and prepare_partitions to be reflected in the
# final initramfs
#
# especially, this needs to be invoked after /etc/crypttab has been created
# for cryptroot-unlock to work:
# https://serverfault.com/questions/907254/cryproot-unlock-with-dropbear-timeout-while-waiting-for-askpass
#
# since Debian buster, it has to be called within create_image() on the $MOUNT
# path instead of $SDCARD (which can be a tmpfs and breaks cryptsetup-initramfs).
