Reduce footprint on arm devices
On arm, we are going to keep the same desktop experience than the desktop one. Streamlining the image removing some packaging and very few light tweaks.

Notes from the session:
Some discussions we can have regarding this topic, ideas where we can look at:
* Looking at the CD manifest, and target potential apps for removal (libreoffice, file-roller, brasero, thunderbird, gwibber, deja-dup, colord…).
Removing uneeded documentation when available disk space is tight:
* yelp doc to remove (as yelp itself).
* manpages & /usr/share/doc (dpkg filtering)
-> check with legal if copyright file can be removed

Do we really want to remove them for a developer image?
~45 Mb, doesn't seem to be a worthy spot
* What about kernels?
-> looking at the size, doesn't seem a blocker as well
* Should we ship the kernel headers?
-> installed by default right now, needed in case you have a special network card needing rebuild
* Watch all python services and see if we can remove/rewrite them in another language to take less memory:
unity-lens-videos
unity-lens-photos
unity-lens-gdocs
eventually unity-lens-

ubuntu-one
Question about having a common seed between desktop and the image proposed for nexus 7
Moving common parts on the desktop-common seed, giving a full unity desktop environment, and having apps then per seed.
OEM project: 1 or 2 Gb are really common, including user data. How to concile this work with other parts of work needed? (like RAM consumption improvment, battery-life…)
deb-src is enabled by default, help to get people starting downloading a source package. It wastes a lot of disk space.
FS nilfs2 seems to be too on the edge for envisionning support and installation by default, but maybe it worthes another look
== Comments ==
2012-11-26 bryce: Dropped -nouveau and -arm for xserver-xorg-video on arm*. These won't be installed by default any more, but will be available for manual installation in the archive. The change is committed to ubuntu-x's xorg git branch; will go out in next upload of xorg package.
