such as headless systems without direct user input. In this situation, it is
advisable to create the key on a trusted local system, and copy the files to the
build system by hand from /var/lib/sbuild/apt-keys/.

Chroot selection
CHROOT The chroot to use. Note that ‘o’, ‘s’, ‘t’, ‘u’ and ‘e’ may be used as
abbreviations for ‘oldstable’, ‘stable’, ‘testing’, ‘unstable’ and ‘experimental’,
