debconf-using program such as d-i; while tasksel will not enable the
backup capb itself, if it is enabled and the user chooses to back up, it
will exit with code 10. Note that this code, rather than 30, was chosen
to interoperate with d-i, which rather inexplicably uses 10 instead of 30
to signal backup across process boundries.
- Fix use of test programs to mark a task to be installed by default.
Only done for --new-install though. Closes: #274933
- To allow tasks with such test programs to co-exist with preseeding
(and not override preseeded values) use the seen flag to tell if
tasksel/first is preseeded.
