<h2>How does NanoBSD work?</h2>
|
||||
<p>
|
||||
NanoBSD is designed to put a possibly reduced FreeBSD system
|
||||
on a Compact Flash card (or other mass storage of your choice)
|
||||
in a way which is suitable for use in appliance like applications.
|
||||
<p>
|
||||
The mass storage is divided into three parts, two image partitions
|
||||
and a configuration file partition, which normally are mounted
|
||||
only read-only. This means that it is safe to pull the power
|
||||
plug on a NanoBSD machine and that Flash based storage is not worn
|
||||
out with filesystem metadata writes.
|
||||
<p>
|
||||
Having two image partitions means that it is possible to download
|
||||
a new image while the system is running, reboot to run that new
|
||||
image and if that fails somehow, it is still possible to switch
|
||||
back to the old image partition.
|
||||
|
||||
<h2>Building NanoBSD images</h2>
|
||||
<p>
|
||||
The Nanobsd build system lives in <tt>src/tools/tools/nanobsd</tt>
|
||||
and consists of makefiles and shell scripts which drives use of
|
||||
the Makefiles in the FreeBSD source tree to create a NanoBSD image.
|
||||
<p>
|
||||
The necessary commands to build a NanoBSD image are:
|
||||
<ul>
|
||||
<li><tt>cd .../src/tools/tools/nanobsd</tt>
|
||||
<li><tt>make</tt>
|
||||
</ul>
|
||||
<p>
|
||||
Depending on your machine, this will take from half an hour
|
||||
to some hours. The process is split into a sequence of
|
||||
steps, and if errors happen underway it is generally, but
|
||||
not always possible to rectify the error and type <tt>make</tt>
|
||||
again to complete the missing steps.
|
||||
<p>
|
||||
If you want to start from scratch you have to delete all files
|
||||
and directories in the NanoBSD directory which start with an
|
||||
underscore: <tt>rm -rf _.*</tt>
|
||||
<p>
|
||||
Here is a breakdown of the files and directories which NanoBSD
|
||||
builds, in the order they are built:
|
||||
<ul>
|
||||
<li><tt>_.bw</tt>
|
||||
<p>The output from running <tt>make buildworld</tt> in the
|
||||
source tree.
|
||||
<p>If this step fails, the output is instead left
|
||||
in the file <tt>_.bw.tmp</tt>
|
||||
<li><tt>_.iw</tt>
|
||||
<p>The output from running <tt>make installworld DESTDIR=_.w</tt>
|
||||
in the source tree.
|
||||
<p>If this step fails, the output is instead left
|
||||
in the file <tt>_.iw.tmp</tt>
|
||||
<li><tt>_.w</tt>
|
||||
<p>This is the directory tree into which installworld installs.
|
||||
<li><tt>_.di</tt>
|
||||
<p>The output from running <tt>make distribute DESTDIR=_.w</tt>
|
||||
in the source trees <tt>etc</tt> subdirectory.
|
||||
<p>If this step fails, the output is instead left
|
||||
in the file <tt>_.di.tmp</tt>
|
||||
<li><tt>_.bk</tt>
|
||||
<p>The output from running <tt>make buildkernel</tt>
|
||||
in the source tree.
|
||||
<p>If this step fails, the output is instead left
|
||||
in the file <tt>_.bk.tmp</tt>
|
||||
<li><tt>_.ik</tt>
|
||||
<p>The output from running <tt>make installkernel DESTDIR=_.w</tt>
|
||||
in the source tree.
|
||||
<p>If this step fails, the output is instead left
|
||||
in the file <tt>_.ik.tmp</tt>
|
||||
<li><tt>_.cs</tt>
|
||||
<p>The output from running the customization scripts in the
|
||||
<tt>Customize</tt> subdirectory.
|
||||
<p>If this step fails, the output is instead left
|
||||
in the file <tt>_.cs.tmp</tt>
|
||||
<li><tt>_.md</tt>
|
||||
<p>The output from building the image file containing the filesystem
|
||||
images of the finished NanoBSD.
|
||||
<p>If this step fails, the output is instead left
|
||||
in the file <tt>_.md.tmp</tt>
|
||||
<li><tt>_.mtree</tt>
|
||||
<p>Mtree(8) output from the files installed into the code patitions
|
||||
in the NanoBSD image.
|
||||
<li><tt>_.i</tt>
|
||||
<p>Image file containing the full disk image. This is the image
|
||||
file you will put on the Compact Flash or other mass storage from
|
||||
which your target platform boots.
|
||||
<li><tt>_.i.s1</tt>
|
||||
<p>Image file containing just the code partition image. This is
|
||||
image you will download to update a running system.
|
||||
</ul>
|
||||
<h2>Customizing NanoBSD images</h2>
|
||||
<p>
|
||||
This is where things get interesting, and where you will be spending
|
||||
your time when developing with NanoBSD.
|
||||
<h3>Storage media size</h3>
|
||||
<p>
|
||||
The first thing you need to configure is how much storage
|
||||
you have on your mass storage media. NanoBSD can work out
|
||||
of the box with as little as 64MB, and if you spend time on
|
||||
it, you can cut it down even further until you end up with
|
||||
an installed system with just the kernel and two or three
|
||||
files in userland.
|
||||
<p>
|
||||
You can determine the size of the storage media with the
|
||||
diskinfo(8) command or by examining dmesg(8) or console
|
||||
output during boot.
|
||||
<p>
|
||||
Once you know the number of sectors on the entire media
|
||||
insert this in the <tt>Makefile</tt> in the definitions of
|
||||
SECTS or pass it as a command line option to make(1) when
|
||||
you build NanoBSD: <tt>MAKE SECTS=100000</tt>.
|
||||
<h3>Storage media geometry</h3>
|
||||
<p>
|
||||
Some platforms need to use CHS addressing in the bootblocks
|
||||
in which case you need to set the <tt>HD</tt> and <tt>SC</tt>
|
||||
values in the Makefile as well. These can also be found from
|
||||
diskinfo(8), dmesg(8) or console output. Even if your current
|
||||
platform does not need these to be set, it is always a good idea
|
||||
to do it anyway.
|
||||
<p>
|
||||
Please be aware that you have to get the values used on the
|
||||
target platform. Putting a CF card in a USB-CF adapter will
|
||||
not result in the correct values for the geometry.
|
||||
<h3>Config partition size</h3>
|
||||
<p>
|
||||
The <tt>DATASIZE</tt> parameter controls how many sectors are
|
||||
used for the configuration partition. Typically you will need
|
||||
very little, but depending on your application and how you
|
||||
organize things, you may want to set this higher or lower.
|
||||
Obviously, the space you use for the configuration partition
|
||||
is not available for the image partitions.
|
||||
<h3>Customize scripts</h3>
|
||||
<p>
|
||||
You can run scripts which will customize the NanoBSD image
|
||||
by listing them in the <tt>CUSTOMIZE</tt> variable in the
|
||||
Makefile. The scripts will be given arguments to show them
|
||||
where everything is and they can do pretty much anything
|
||||
they want to do to the directory tree.
|
||||
<h3>Slimming down FreeBSD to fit</h3>
|
||||
<p>
|
||||
The <tt>make.conf</tt> file overrides the usual <tt>/etc/make.conf</tt>
|
||||
and by default disables a lot of FreeBSD from the build in order to
|
||||
make it fit on 64MB devices. Go through the list and decide if there
|
||||
are anything you want or do not want in your NanoBSD image.
|
||||
<h3>Slimming down the kernel</h3>
|
||||
<p>
|
||||
You may also want to use a kernel other than <tt>GENERIC</tt>.
|
||||
Put the config file in <tt>../../../sys/i386/conf</tt> and
|
||||
set the name in <tt>KERNCONF</tt> in <tt>make.conf</tt>.
|
||||
<p>
|
||||
You can save a couple of megabytes of space in your image by
|
||||
removing all the bits you will not need. (How many appliances
|
||||
need support for nine different RAID controllers ?)
|
||||
<h2>Provided customize scripts</h2>
|
||||
<p>
|
||||
By default the following customize scripts are provided (but not
|
||||
called unless you list them in <tt>CUSTOMIZE</tt>.
|
||||
<h3>comconsole</h3>
|
||||
<p>
|
||||
Disables getty(8) on the VGA devices and enables console in the
|
||||
COM1 serial port.
|
||||
<h3>nobeastie</h3>
|
||||
<p>
|
||||
Disables the "beastie-menu" in the bootloader.
|
||||
<h3>NET4801</h3>
|
||||
<p>
|
||||
Disables ata-dma for the Soekris NET4801 because early hardware
|
||||
versions do not support DMA on the CF socket.
