dchroot-dsa binary package in Ubuntu Xenial arm64

 dchroot allows users to execute commands or interactive shells in
 different chroots. A typical installation might provide 'stable',
 'testing' and 'unstable' chroots. Users can move between chroots as
 necessary.
 .
 This package provides a dchroot-dsa binary which is compatible with
 the command-line options and configuration file format used by the
 dchroot-dsa dchroot maintained by the Debian System Administrators
 used on machines administered for the Debian Project.
 .
 NOTE: the schroot package provides a better implementation of
 dchroot-dsa. In particular:
  * dchroot-dsa only allows the specification of a single command with
    an absolute path, and no options may be used with the command;
    schroot allows the use of relative and absolute paths with no
    limit on the number of options.
  * dchroot-dsa only allows one chroot to be used at once; schroot will
    allow the use of as many chroots as desired.
  * dchroot-dsa allows access to be restricted to named users; schroot
    implements finer-grained access controls based on users and groups,
    either of which may be granted the ability to gain root access to
    the chroot if required.
 Using schroot will avoid these issues, as well as provide significant
 additional functionality dchroot-dsa does not possess.
