Ths first line ('... boolean true') is needed to trick debian-cd into
believing that the type of the question is a boolean.
Otherwise debian-cd will think that the question doesn't exist, probably
because it doesn't know the type, probably because there's no type to
start with (this is an error message, not a question).
FTR, without the first line, it fails with:
2022-08-04 10:05:37,846 DEBUG Checking configuration...
error: Cannot find a question for encfs/security-information
2022-08-04 10:05:38,016 ERROR preseed file invalid:
<<LBDIR>>/simple-cdd/profiles/kali.preseed
In theory, this change is not really needed here because the
package is not installed by d-i, it's already installed by live-build
in the live image. But I want this file to be consistent with the
version in debian-installer...
* Add new --variant option to build alternative images of Kali.
* Add new --version option to decide of the name of the generated file.
* Add new --subdir option to indicate where the image must be moved.
