Don't let this slow you down. Tag your packages as dist-olpc4. I just
did these for the 3 you have already done (thanks!). They will appear
in joyride later tonight.

Thanks. With the Fedora 9 upgrade, we found it really useful to have a
wiki page listing the outstanding regressions that were related to
upgrade fallout. I created one here:
http://wiki.laptop.org/go/OLPC-4
and populated it with the parts from
Distro_version_migration_nastiness that I think need to be fixed for
F10/9.1. Feel free to update and modify as you see fit, or ignore if
you think it is useless :)

Agreed, and now is the right time in the cycle.

Sounds good. I think you will find that some are harder to fix, even
though they are entirely Fedora, because OLPC has different
requirements from your normal desktop users. Let's see how we get on
:)

OK. I want to help with some of this, I did a lot of the work for F9
so know what to look for and how to address these things. Expect some
bugs coming from my end :)

Our smallest release by far was ship2. The above pages show it as
bigger than 8.2, but actually ship2 includes activities and library
content (over 100mb, I think) which we exclude from later builds and
install separately.

ship2 including activities and library is 279mb.
8.2-g1g1-767 including activities and library is 450mb.

Not a fair comparison because 8.2 includes more activities, including
the 100mb WikipediaEN, but the point is there: we are continually
getting bigger and it is a difficult battle to keep things the same
size, never mind making them get smaller.

I think you can run the joyride images in emulation. I also think its
about time we got you an XO. Submit an application here:
