Re: RFC: bringing back task packages

[Not sure whether we should keep the long To: - list, I'd suggest
 continuing on debian-devel but keep it for the moment.]

If I understand the consequences of the statement correctly I welcome
this step very much.

Yes, definitely!

This would be an acceptable approach.

The requirement for a limited set of tasks to provide a good overview is
reasonable but has two flavours:  On one hand it restricts the number of
Blends we can include into the list and on the other hand it might have
an influence on the number of "tasks"[1] we are maintaining inside each
Blend which exceeds 10 drastically at least for three Blends (the most
active ones).

>From my perspective the only reasonable solution for this "reduced
number of list entries" requirement is to close bug #273797 and have a
hierarchical task selection where you first select the Blend and than
select a set of "tasks"[1] inside the Blend.

Remark: I have the feeling that in the Blends context we are using the
term "task" in some different manner.  While it was probably influenced
by tasksel (and invented by the Debian Edu developers) it drifted a bit
away somehow.  I have the feeling that we should find a proper
definition what we mean when talking about Blends.

I'm afraid I do not fully understand the difference / consequences of these
two options.  Can you provide some short examples?

Kind regards
