FOSDEM talks/slides: pkgsrc on MirBSD, pkgin (Updated)
Last weekend the Free and Open Software Developer Meeting (FOSDEM)
happened. As in previous years, there was a booth manned by
people from various BSD-projects, and there were also
two(?) talks related to NetBSD and its related project pkgsrc:
Thomas 'wiz' Klausner pointed out that there was
actually a whole "BSD Devroom", and there were
many BSD-talks there, including:
- NetBSD and MirBSD developer Benny Siegert gave a talk titled
"pkgsrc on MirBSD" -
see his slides! pkgsrc is a framework for packaging and building 3rd party applications from source. Besides MirBSD, it runs on many
other platforms like Linux and Mac OS X.
- While building from source is fine, it costs a lot of time.
pkgsrc can also create binary packages, and to manage those,
there is "pkgin", a binary package manager.
Its developer, Emile 'iMil' Heitor
introduced it in a talk -
see the slides (PDF)!
Besides other talks that were less focused on NetBSD/pkgsrc,
this event shows that there's a pretty active group of
BSD advocates in Europe that manage to advocate "BSD"
in its entirety pretty well. Well done, guys!

BSDCan 2012 - call for papers (Updated)
Watching conference proceedings and publications like magazines,
I feel a certain lack of NetBSD presence. Even in events that
are BSD-friendly (EuroBSDcon, BSD Magazine come to mind).
So here's a friendly reminder to go out on the street
and preach the truth, as
posted by Dan Langille on netbsd-advocacy@:
You have two days left before the deadline!
``BSDCan 2012 will be held 11-12 May, 2012 in Ottawa at the University of
Ottawa. It will be preceded by two days of tutorials on 9-10 May.
NOTE: This will be Fri/Sat with tutorials on Wed/Thu.
We are now accepting proposals for talks.
The talks should be designed with a very strong technical content bias.
Proposals of a business development or marketing nature are not
appropriate for this venue.
If you are doing something interesting with a BSD operating system,
please submit a proposal. Whether you are developing a very complex
system using BSD as the foundation, or helping others and have a story
to tell about how BSD played a role, we want to hear about your
experience. People using BSD as a platform for research are also
encouraged to submit a proposal. Possible topics include:
From the BSDCan website, the Archives section will allow you to review
the wide variety of past BSDCan presentations as further examples.
- How we manage a giant installation with respect to handling spam.
- and/or sysadmin.
- and/or networking.
Both users and developers are encouraged to share their experiences.
The schedule is:
8 Jan 2012 Proposal acceptance begins
29 Jan 2012 Proposal acceptance ends
19 Feb 2012 Confirmation of accepted proposals
Instructions for submitting a proposal to BSDCan 2012 are available
The deadline for submissions has been extended to Tuesday 31 January.

NYCBSDCon 2010 Call for Papers
Citing from the
call for papers:
``The New York City BSD Conference (NYCBSDCon) is the main technical
conference on the US East Coast for the BSD community to get together to
share and gain knowledge, to network with like-minded people, and to
have fun. This event is organized by members of the New York City *BSD
Users Group (NYC*BUG).
The NYCBSDCon program committee is accepting submissions for
imaginative, embryonic and energizing presentations surrounding the BSD
operating systems. We are looking to attract a wide range of speakers
and attendees; therefore, topics of interest range from the esoteric to
development to practical, everyday sysadmin life. Of course, original
topics are preferred in most cases.

More news from NetBSD land: inside and outside the kernel
My inbox is still overflowing with NetBSD related news,
so here is the next chunk for you:
I'm closing for today by pointing to three NetBSD-related events:
- People owning a Marvell PCMCIA WiFi card can how have
a look at
the malo(4) driver.
If you use this on a gumstix ARM board, have a look
as some fiddling with drvctl(8) is needed to get the
card recognized properly.
- Speaking about
KIYOHARA Takashi has declared the
porting effort as finished.
Support for the baex, connex, verdex and verdex-pro
modules is available, as is support for the support modules.
Staying in the "embedded" corner, KIYOHARA Takashi has
that Plathome's OpenBlockS600 (AMCC 405EX) can now
boot NetBSD via NFS. See the posting for dmesg output.
comes with a AMCC 405EX PowerPC CPU,
two GigE ethernet ports and a bunch of other
goodies for a price of about $600US.
- Coming from hardware to software,
was released some time ago, and of course
binary packages are available
for a number of platforms:
4.0.1/sparc and 5.0.1/sparc,
4.0.1/i386, 5.0.1/i386 and the same for 4.0.1/amd64 5.0.1/amd64.
Also, binaries of pkgsrc-2009Q3 are available
Summer of Code
was a big success for NetBSD and all of the Open Source
community, and it seems
there will be one again
Preparations are in an early stage, but there are already
a FAQ and
as well as the
Program Terms of Service.
From the NetBSD side, we're always happy for project suggestions
(please use our mailing lists for discussions),
and in NetBSD, we are currently working on out
If you plan to submit a proposal for a project

- Getting back to the NetBSD code, a number of interesting changes
were made in the previous weeks. The first to mention is that
David Young has continued is work on
the new shutdown order
for device drivers:
``cgd, dk, dm, md, raid, and vnd gracefully detach from the device
tree during shutdown. I believe that ccd is the only virtual disk that
does not detach.''
This allows having arbitrary stack of file systems, and still
have them unconfigured properly in the right order on system
- Another major change that went into NetBSD recently is that
terminfo was imported into NetBSD-current.
Terminfo replaces termcap, but provides a
backward compatible termcap interface.
This move follows
discussion from last summer,
docs by The Open Group (the people who make
things like the POSIX standard and the Single Unix Specification),
which indicates that the termcap specification will be
withdrawn in the future.
- Moving from userland inside the kernel, David Holland has
proceeded with work to
unhook LFS from UFS.
Historically, the Log structured File System was written after
the Berkeley Fast File System. With the idea of sharing
the core "Unix File System" code for both file systems,
this resulted in a strong relationship between LFS and FFS,
which was/is not always the best for the advantage and
stability of either one:
``sharing ufs between both ffs and lfs has
made all three entities (but particularly lfs) gross. ffs and lfs are
not similar enough structurally for this sharing to really be a good
- Another major addition to the NetBSD kernel was made recently
by Darren Hunt:
``Courtesy of CoyotePoint Systems, I've been working on a port of
DTrace [...] to NetBSD for i386.''
``DTrace is a comprehensive dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time. Originally developed for Solaris, it has since been released under the free Common Development and Distribution License (CDDL) and has been ported to several other Unix-like systems.
DTrace can be used to get a global overview of a running system, such as the amount of memory, CPU time, filesystem and network resources used by the active processes. It can also provide much more fine-grained information, such as a log of the arguments with which a specific function is being called, or a list of the processes accessing a specific file. ''
The code is available in NetBSD-current. I haven't looked
into this yet, but I'm looking forward of reports and blog
the wikipedia command line examples work.
(I think like with ZFS, Dtrace could use a hand with
documenting the NetBSD side of things. Any takers?)
- The last kernel change to mention is related to security:
mapping the address 0 from userland was disabled.
late last year, and
it this is now addressed in NetBSD, too.
Those that still beed to map address 0 can do so via
the USER_VA0_DISABLED_DEFAULT kernel option
or the vm.user_va0_disable sysctl.
So much about about the NetBSD code for now. Of course having
all those fine features added screams for an immediate (*cough*)
release, which brings me to the fact that
NetBSD 5.0.2 has been released:
`` NetBSD 5.0.2 is the second critical/security update of the NetBSD 5.0 release branch. It represents a selected subset of fixes deemed critical for security or stability reasons.
Please note that all fixes in critical/security updates (i.e., NetBSD 5.0.1, 5.0.2, etc.) are cumulative, so the latest update contains all such fixes since the corresponding minor release. These fixes will also appear in future minor releases (i.e., NetBSD 5.1, 5.2, etc.), together with other less-critical fixes and feature enhancements. ''
Have fun meeting the gang!
- There's a
going this weekend (Feb 20/21 2010)
- Volunteers are wanted to setup & man a NetBSD booth at
FrOSCamp 2010 Zurich, Switzerland, on Sep 17/18 2010
- pkgsrcCon 2010 will be held in Basel, Switzerland, from
May 28ths to 30ths 2010.
