I don't know if the normal way would not have provided a smaller package. Else, in Virtualbox I am not sure it is the best to provide feedback. It would be nice if some real machines would be used to see how it goes.
Now I do RC4, RC5, and RC6.
RC4 is the return of the former icons. Of course, updating is still a priority.
RC5 is the coming of a few apps, gxine, exaile, that kind.
RC6 will be the same as RC4 and RC5, plus some libreoffice packages. It's on test now and will be on a T30 (IBM laptop with 512 MB ram and processor Intel P4 with 1,84 Ghz, which boots on a 1.1 USB.
)
Somewhere in the middle I added again update notifier and the Ubuntu software center (that helps the newbies very much to find apps they don't yet know about). I had an issue with error messages at the boot of the live : I solved it using the dirty way, I remove the file software-properties-gtk.desktop from /etc/xdg/autostart in the build directory. This is the program which is linked to update notifier and provides the gui configuration for the repositories, frequency of updates and such.
I'll probably upload them 3 soon, one after the other.
