I have packaged nodm version 0.7 in wip/nodm, but it doesn't build on 
NetBSD (needs libpam_misc notably). There appears to be a special version 
maintained by Debian which is intended to work on kFreeBSD, but I didn't 
have the time to look at it yet.

Cheers,

Check how Live CD is done.  It's not in the tree, I think.

Or use md(4) to embed custom fs image into the kernel, like

Probably.  You might experiment with running something other than getty
in /etc/ttys - maybe try login(1), maybe try a shell....

There are two similar things I'm sure could be done: (1) use a
passwordless account for logging in to NetBSD, which isn't quite
auto-login but can feel like it in some human respects, and (2) start X
at boot - like an xdm setup, only X is run without -query, so it starts
a local session instead of contacting a remote xdm server.

Obviously, this (especially (2)) isn't auto-login in general, just
something that may address the underlying desire that led you ask about
auto-login.

Andy Ball — 2013-03-13T15:17:34

Hello,

    Experimentally I have created a USB flash drive that
an old PC can boot.  Once the user logs in to NetBSD, it
starts X and launches a full-screen rdesktop connection
to a Windows server, where the user then logs into his or
her Windows account.

    Is it possible to make NetBSD automatically log a user
in on the console so that people don't have to log in twice
(once to NetBSD and once to Windows)?

    How would I go about turning that USB flash image into
something that I can boot from a DVD and then run in a RAM
drive?  Any advice would be most welcome.

flash file system options

Ed Sutter — 2012-10-23T14:06:58

Hi,
I'm new to this list, so I apologize if this is the wrong forum for this 
question...
Years back I wrote a boot monitor called MicroMonitor 
(http://www.umonfw.com) that
has its own very basic, but quite useful flash-file-system (dare I call 
it that).
Anyway, I'm trying to upgrade this to something that supports 
NOR/NAND/eMMC plus
wear leveling and I'd certainly like to avoid doing this from scratch.
Ideally, I'd like to do this with source code that is licensed as BSD.

I've seen CHFS and NANDFS under various NetBSD trees but before I go off 
and try to
pull them out on their own, I'd sure like to hear what anyone knows 
about these
(and other) flash file systems.

Anyone have any thoughts/comments/suggestions?
Thanks,
Ed

NetBSD port for AT91SAM9G20?

Jukka Marin — 2012-09-05T06:43:56

Hi,

I have asked this before, but got no replies.  We are making AT91SAM9G20
based hardware and I would love to run NetBSD on it.  However, I can't
find the time to port NetBSD to this MCU and hardware.  Is there anyone
with some spare time and interest in this kind of a project?  I could
provide the hardware and documentation required.  I might even sponsor
some $'s to the NetBSD project if I could run my favourite OS on our
hardware.

The main features of our current hardware are:
- AT91SAM9G20 MCU (400 MHz)
- 64 MB RAM
- 128 MB NAND FLASH
- 8 MB NOR FLASH
- hardware watchdog
- RTC with battery backup
- 4 x 10/100 Mbps Ethernet (with a switch)
- 3 x RS232
- 2 x RS485
- 3G GSM modem
- digital inputs (opto isolated)
- relay outputs
- LEDs
- USB host / device ports
- expansion slot
- power supply 9...30 VDC
- 19" rack mount case (or a smaller metal case)

Thanks!

That's the magic. You've measured your power consumption.

    What about configuration: Do you turn down the logging
or do anything to stop NetBSD mailing root every day?

    I understand what you're saying and clearly it will
depend what you're comparing the machine against.  Older
light servers can sometimes be useful as edge devices
where you want one device to do specific light-duty
work: In the past I've used them for print servers and I
currently run a Pentium III (burns <30 Watts) as a
terminal server, providing SSH access

That is almost certainly not true. Power requirements for any given unit work of are dropping all the time, so it isn't hard to get new hardware that will be much more efficient than old hardware. By efficient, I mean CPU throughput per watt, although power supply efficiency is also improving. Last year I finally bit the bullet and replaced a small bunch of sparc64 and i386 boxes with a single Xen server. Everything runs faster, my electricity bill went down and that room is no longer the warmest room in the house. If it will do the job, just buy an Intel Atom.


I have a system for building images to do that at http://home.must-have-coffee.gen.nz/hg/software/miniaturise/. It does have a couple of flaws: 1) it can use syspkgs, but syspkgs isn

    Do you pare down your router/firewall installations?
What are you able to omit Vs. an ordinary NetBSD server
installation?

    I understand those are quite energy-efficient. RAM might
be quite expensive if you don't already have it laying
around though.  I think the only SPARC hardware I have left
is a Krupps that I would like to configure as an X terminal.
I need to learn how to net-boot it though and how to tailor
a NetBSD image for a diskless environment (for this and
other embedded applications).

Re: Z80s and 6502s

  Nope.  Sadly I do nearly all of my embedded development under Linux
and Solaris these days.  I run lots of NetBSD machines, but they're all
"production" roles, usually as firewalls and routers, mostly at customer
sites but one here.  I use sparc64 (Netra X1s mostly...tiny, cheap, low
power) for that stuff.

  I do some work in support of the SDCC project; it targets Z80 as well
as many other "small" processors, but not 6502.  The snapshot builds of
SDCC are done here on my network, including the binaries for
NetBSD-i386.  I have a biggish VMware ESXi host system here and that
test/build machine resides on there.
