Paul, this is a question I have asked too (and I am not "flaming"
your answer by what I am about to say, just using it as an example of
a broader issue!).
I think I have adequately humbled myself in other posts by defining
myself as a N00B. That is not entirely true as I have been working
in the PC world since the days of CP/M, but where Linux is concerned
I characterize myself as a "user" rather then a "developer", even
though I can generally read source code in most languages.
I subscribe to the "Angstrom-distro-users" list and not the
developer's list for just that reason. My Zaurus is a valuable tool
in my work with wireless networking security, but I don't have the
time or the inclination to get into compiling my own kernel. I am
extremely grateful to the OpenEmbedded group and have expressed my
gratitude in a financial way in the past.
That is not bragging. Each of us in the community has something to
contribute, and not all of us are coders or even able to read a
source file. For example, I had a lot of trouble getting WPA/PSK to
work on my Akita, and when I finally succeeded I updated the Wiki. I
hope what I put there is correct. I know it worked for me.
In a similar manner, if I can find out what each of the distribution
file names means, I will update the Wiki.
At present there are five different image files in the Akita download
area:
console-image
minimalist-image
x11-image
x11-image (summary)
and finally, x-11-image-akita (with no date information).
It's fairly evident to me what the console image is; I don't know how
much less would be included in the minimalist image, and like Paul
M., I don't know what is included or not in the "summary" version.
In the hyperlink you provided, the comments under "JFFS2_SUMMARY" say,
"1236 This feature makes it possible to use summary information
1237 for faster filesystem mount.
1238
1239 The summary information can be inserted into a
filesystem image
1240 by the utility 'sumtool'.
1241
1242 If unsure, say 'N'."
Sorry, that doesn't mean much to me, in terms of which version of the
image I should load on my Zaurus. Does it mean that the compilation
will run faster, or that the target machine (Zaurus) will run (or
boot) faster?
By experimentation, I found that the last file, the file without date
information embedded, worked the best for me.
Now, what's the intention of the tarballs? are they for "bit-baking"
your own version? or for compiling on the Zaurus? Just a few notes
in README file or on the wiki would go a long way to reducing the
confusion.
I've been frequently frustrated on this list by the lack of
information useful to inexperienced users, especially as compared to
the communities surrounding some of the older Zaurus ROMs. Since
Angstrom is the way of the future for Zauri, I am committed to
helping in whatever ways I am able. I will try to contribute to the
wiki as I learn, but some help and understanding from the more
experienced members of the community would go a long way.

What is the difference between the files with "summary" in the name
(which are bigger) and those without?
Here's file from the kernel tree which defines corresponding option:
http://git.kernel.org/?p=linux/kernel/git/torvalds/
linux-2.6.git;a=blob;f=fs/
Kconfig;h=58a0650293e19082ad2b4f951d17a35b78f9224a;hb=HEAD
(search for "summary"). That's as authoritative description as it can
get. Use google to find more info. I personally can't add any
commentary as I never used this options/images with it.
