+Description: Which script should be used for partitioning?
+Extended_description: The path should be absolute, and the script must
+ be executable.

+Template: fripost/wipe-device
+Type: select
+Default: zero
+Choices: none, zero, urandom, random
+Description: Which kind of data fill the disk with before encryption?
+Extended_description: 'none' means disks will NOT wiped, otherwise use
+ /dev/{zero,urandom,random} as the source data to fill disks with.
+ Beware that the later two may drain the entropy pool of the system!

+Description: Press 'continue' once you have sent the key
+ You now need to send the encryption key for the LUKS/dm-crypt volume to
+ this special-purpose SSH server:
+ .
+ ssh -o UserKnownHostsFile=/dev/null -T root@${IPv4} < /path/to/key
+ .
+ To defeat MiTM-attacks, please ensure that the server fingerprint matches
+ .
+ ${SSHFPR_SERVER}
+ .
+ Key(s) that are granted access have the following fingerprint:
+ .
+ ${SSHFPR_AUTHORIZED}
+ .
+ Note: This server is ephemeral, and will be replaced with a full-blown
+ daemon toward the end of the installation. Using /dev/null as the
+ Known Hosts File is meant to tell the SSH client not to remember its
+ public key.
