The big one here is kernel kernel kernel.

Or even the 1.5, I believe most of the XO-1 support is upsteream.

Yes, and no. I mean 1Gb of the original XO-1 is tight, but SoaS still
happily fits in 4Gb with a bunch of space to spare. Looking at my
current SoaS VM the used space is around 1.9Gb. Amusingly the various
cloud/container enterprise initiatives actively help us here because
for once they care about dependency bloat too :-)

The two things that add bloat to the current SoaS image are:
* Browse needs to be converted to the new WebKitGtk APIs so we don't
ship two copies of WebKitGtk.
* Conversion of remaining gstreamer 0.10 to 1.0 to allow us not to ship that.

Ultimately I think you could with a little development effort get it
down to 1.5Gb used space which would make a 2Gb filesystem quite

Personally I have no interest in that. I wish you luck.
