I see http://wiki.netbsd.org/amazon_ec2/ now lists ami-fe7c8f97, which
comes up and looks good, but I discovered the following slight problem:

# ls -l /dev/null
-rw-r--r--  1 root  wheel  0 Mar  2 17:15 /dev/null
# 

It'd also be really neat if we could have an AMI with both pkgsrc and a
populated /usr/src.

I'm looking into building such an image myself following the
instructions on the twiki, but if anybody else beats me to it, I'm sure
others would find that useful.

Borked pkg_add. I chroot()ed in the partition for 5.1, and executed a
pkg_add bluntly, which creates /dev/null through a pipe redirection.
Will fix that for other regions too.

Hmm. I have a problem there. While I can maintain NetBSD x.y
approximately sane from an "up-to-date" point of view, I won't rebuild
AMIs just for the fun of repackaging src/ and pkgsrc/ on a regular basis.

Beware of packaging AMIs this way, unless you intend to maintain them in
the long run by regularly reuploading/cvs upping the image. Compared to
stable releases, src and pkgsrc are moving targets, and you can quickly

But why wasn't /dev populated?  Or did you run MAKEDEV after?

If you include an up to date (when you build the AMI) checkout of
/usr/src, the consumer can just run "cvs update" as desired to fetch the
new revisions.  It saves a lot of I/O.

Yep, the tar file is missing the /dev content

This is somewhat mitigated by init(8), as it executes MAKEDEV if
/dev/console is missing (IIRC). But MAKEDEV won't overwrite a node if it
is already present, and given that /dev/null is...

Fair enough :) Will do.

I don't think it's "missing".  It is intentional that none of the tar files
contain the contents of /dev, because extracting the tar file on a
system with an incompatible interpretation of the device major and minor
numbers would give a result potentially much more harmful than an
empty /dev.  So running MAKEDEV *on a NetBSD system of the right
architecture* after extracting the tar file is an important thing to do.

Also, this way you don't get persistent device permissions.

BTW: /dev populated, src/ and pkgsrc/ are present too (but I would
recommend cvs up'ing first, heh).

building ec2 amis

Hello,

I'm trying to follow http://wiki.netbsd.org/amazon_ec2/ to build a new
AMI, but I've not been successful.  After

su root ./build.sh -O ../obj -T ../tools -D ../dest -R ../release -U -V \
	INSTALLSETS="base etc" install=/mnt/ec2

I find that /mnt/ec2 looks not completely populated.  /mnt/ec2/etc/rc.d/ is
empty, as is /mnt/ec2/etc/ssh/; running

makefs -t ffs -B le -s 256m -N /mnt/ec2/etc/ -o density=32k \
	/tmp/NetBSD-AMI.img /mnt/ec2/ 

then yields:

makefs: Unable to use user and group databases in `/mnt/ec2/etc'

Is it possible that there are some steps missing from the wiki?

-Jan

 Most likely, the etc set is not extracted, because of [1].

 You need a -current updated src/; patch for -5 has a pull-up request. 
 But it's still in the pipe, as it is a commodity fix.
