My misunderstanding was that Ububtu Touch is a simple extension to standard Ubuntu like Xfce or LXDE or Gnome (this is also the way QtMoko or QuantumSTEP are built) and not a separate system with its own rootfs management philosophy. >> * how is it installed? does a "apt-get install ubuntu-touch" suffice? > Unfortunately no.

How > about tinkerphones? The GTA04 has (depending on production variant) between 512MB and 1GB RAM + 512MB to 1GB NAND flash + µSD up to 32GB (maybe 256 GB also works). A potential Pyra-Phone (if it is ever built) could have 2-4GB and up to 3 µSD with up to 256 GB (and even more if one can afford). And if that is not enough it would have an SATA port for external storage :) BR, Nikolaus ___ Community mailing list Community@tinkerphones.org http://lists.goldelico.com/mailman/listinfo.cgi/community http://www.tinkerphones.org

That is a really interesting idea full in line with our overall goals. There was
some interest 2 years ago, and we already had installed a mailing list:
http://lists.goldelico.com/mailman/listinfo.cgi/gta04-ubuntu-touch
But it remained almost inactive. So let me invite you to just make use of it.
Your initiative can make the ball rolling again.
Let me ask some question that come to my (naive) mind:
* how does ubuntu touch differ from desktop ubuntu?
* do they share apt-get repositories?
* how is it installed? does a "apt-get install ubuntu-touch" suffice?
* what are minimum requirements to memory, screen resolution?
