## Opinions

I've discussed the state of Desktop NetBSD Project (DNP)
with various developers on IRC and in mail,
and I've received different opinions on how developers view it.

I shall not discuss problems arising from lack of hardware drivers,
most notably network interfaces, wireless and "wireful," and
graphical adapters.
I'm concentrating on more general questions here.

### Binary packages

One of perceived problems (mbalmer) is that we don't have
any toolkit for graphical user interfaces in base, and thus
we don't have any chance to write anything with GUI.
It is opined that the lack of applications readily available
(that use this toolkit) is less important; since there's no
toolkit, no applications are available.

Another perceived problem is lack of binary package updates in pkgsrc.
I still don't understand what exactly is the problem here,
and nobody cared to provide elaborate explanation what it is.
We have several different ways to manage software installations
using binary packages.
Besides using pkgsrc in a way to reuse binary packages
("bin-install" in DEPENDS_TARGET),
there exist pkg_chk with support for binary updates,
and there exists pkg_rolling-replace, which, I think,
can be set up to reuse binary packages as well.

My perception of this "binary packages problem" is that it is imaginary.
I've heard some loud praises of pkgin, but I haven't heard more than
several voices. Thus I'd rather attribute this problem either
to the lack of experience, or to the lack of documentation,
or very scarce publicity rather than lack of support.
I don't deny though, that there exist real problems
which may prevent users from using pkgsrc effectively.

### X11

Tobias Nygren (tnn) suggested idea that removing from base
can free human resources and help development of more coherent system.

Indeed, moving base X11 version into pkgsrc has brings at least one major benefit:
it is much easier to update a package than part of base system.
Also, pkgsrc has much shorter release cycle, a quarter rather than
two or three years. This means that developers can spend their time
more effectively, they can save time otherwise spent in adaptation
of new packages to older libraries, drivers, or applications
as found in older NetBSD releases.

It was argued (joerg) that there're very few sensible reasons
to continue development of base, one of them is
cross-compilation, another one is ease of development.
pkgsrc provides some cross-compilation support for quite a long time;
there exist documents describing how to utilise it, and one of them
addresses cross-compilation of (modular) specifically.
Thus the only reason remains: ease of development.

I've heard two different opinions related to the ease of development.
David Holland pointed out that we need topic-oriented patches in pkgsrc;
this needs pkgsrc tools with functionality similar like quilt.
Tobias Nygren expressed more radical view, that
convenience of two or three developers shouldn't hold the whole project.

It should be possible to help the transition by using
support for CVS-based packages from pkgsrc-WIP.
In my opinion, this could be used to help hackers
working with CVS version (xsrc module) during development cycle.
NetBSD could distribute its own version for some time,
which could co-exist with pkgsrc's version for some time.
This idea met rather strong opposition,
but I don't really insist on performing transition exactly this way.

### Applications

#### Priorities

It would be nice to have a list of important packages.

While sometimes it may be hard to come to consensus,
there exist packages which are unique (Firefox, OpenOffice)
or where there're few important alternatives.
A (prioritized) list of them would be nice to have.

An approximation of it could be a list of packages most used by users.

Each quarter we ask users to provide information on installed packages:

"We'd also really appreciate it if people would install the
pkgsrc/pkgtools/pkgsurvey package, and then run the pkgsurvey script for us.
This will forward us a list of the packages installed on that machine,
and the operating system and release level of the operating system.
The results will be kept confidential, but the output will help us analyse
the packages that are most used."

It is not clear

* why the information is kept secret;
* if there's enough statistics being gathered;
* if this information is used at all.

Perhaps we should publish it or start publishing it in future.

#### Release cycle

We need someone running pkgsrc bulk builds from current tree before freeze.

We don't even see build problems before first bulk build results,
which appear closer to planned end of freeze.
Sure, knowing of problem existance doesn't automatically entail quick fix.
But we don't even know that the problem is there at the first place.
(E.g. in 2010Q4 freeze the problem with renderproto package
was discovered 3 days before the freeze ended.)

We need pkgsrc bulk builds with modular

In many cases base is too old to provide necessary hardware support,
significant number of users are forced to use pkgsrc

### Organisation

It is obvious from above, that many problems need organised effort to be solved.
Some of them are rather large to be worked on singlehandedly,
others require cooperation of some other developers or even users.

It isn't clear if we can get out of base in realistic future,
since it requires cooperation of unnamed hackers and, perhaps
and most possibly, some other developers.

It isn't clear if we can get realistic picture of pkgsrc usage at all,
since it requires cooperation of users, at the very least.

It isn't yet clear if we can get realistic description of use cases
of binary packages let alone improve anything in this area.
This requires rather long period of maintaining different systems
in different ways and by different people.

What is clear, in my opinion, is that we have organisational problems
and very passive community. There's very strong faction of developers
and users who want Unix as it was decades ago.

### Unsorted/unprocessed

* lack of interactivity support in pkgsrc tools
* NetBSD-specific problems in (possibly connected to 64-bit time_t):
touchscreen looses ButtonRelease events,
problems with X_GetImage (in Xnest and other applications, e.g. FriCAS)
* touchscreen calibration support
* X server which doesn't need configuration file
* "Distribuition" based on NetBSD?
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  73 (X_GetImage)
