# This script will run in the initrd environment at boot and edit

# /conf/conf.d/cryptroot to set /lib/mandos/plugin-runner as keyscript
5
# when no other keyscript is set, before cryptsetup.

# This script should be installed as

# "/usr/share/initramfs-tools/scripts/local-top/mandos" which will
10
# eventually be "/scripts/local-top/mandos" in the initrd.img file.

# No initramfs pre-requirements; we must instead run BEFORE cryptroot.
13
# This is not a problem, since cryptroot forces itself to run LAST.
