(writing from my phone) I'm not sure if this is still true, but a few weeks ago porters were recommended to just use the old "cdimage-style" flipped model. It means to just have the extractes rootfs files in /data/ubuntu and the Android system.img copied in there, which happens automatically when flashing the rootfs in ubuntu_deploy.sh. The system partition just contains android stuff with the usual ubuntu patches.
The new "system-img-style" (it's called something like that but not exactly that iirc) requires a special server to allow OTA updates. That server also converts the files available at cdimage.ubuntu.com to something different. It was supposed to be ready for testing with ports soonish, but so far I haven't heard any news about it. That server also changes the way swap works afaik. I think the "supporting ports" thing is something that some of the canonical employees consider important, so depending on who is responsible for some feature, you may get a fast response on IRC. (otoh, some employees would love to drop deprecated stuff like surfaceflinger, which is still absolutely required for some ports but slows ubuntu development speed. I.e. some of them dont care about ports at all, so.. Good luck. ) Cheers Florian Am 18.11.2013 09:56 schrieb "François Leblanc" <fleblan...@gmail.com>: > > > I agree this is not clear for me too. > > I notice some differences betwen using ubuntu dir and system.img in the structure of files and even if it is more simple to use dir ubuntu it is quite difficult to understand how system.img must be. > > According to touch script in build kernel they are some files that must be present but I don't find any documentation about this, system.img for example to be put in /var/lib/lxc/android/system.img, swap file is named SWAP.swp in touch script and SWAP.img in trusty-touch-preinstalled-armhf.zip ... > > Regards, > François. > > > > > > 2013/11/18 Dmitry Smirnov <divis1...@gmail.com> >> >> Sorry for bothering you again, but I did not understand what is meant to be new and old flipped models. >> 'touch' script is using /data/ubuntu as an old model (where /data is the 'userdata' partition). >> At the same time ubuntu_deploy.sh (included into cdimage.ubuntu.comzips) >> unpacks tar.gz into /data/ubuntu. >> So, there is some mismatch, right? >> >> How this cdimage zip is supposed to be deployed for new flipped model? >> >> >> >> >> 2013/11/6 Oliver Grawert <o...@ubuntu.com> >>> >>> hi, >>> Am Mittwoch, den 06.11.2013, 12:49 +0200 schrieb Jani Monoses: >>> > unflipped will not work anymore, all the super evil hacks it used are >>> > gone from the rootfs since over 6 months, please only use (and >>> > recommend) the flipped method. >>> > >>> > >>> > >>> > From the recent thread on this list saying the cdimage-legacy option >>> > of phablet-flash is to be kept around I figured that unflipped images >>> > are still around >>> >>> the cdimage-legacy install variant is still available in phablet-flash, >>> it installs the mobile world congress demo from feb. which has pretty >>> pictures instead of apps. >>> >>> we stopped building such images long ago ;) >>> >>> ciao >>> oli >>> >>> >>> -- >>> Mailing list: https://launchpad.net/~ubuntu-phone >>> Post to : ubuntu-phone@lists.launchpad.net >>> Unsubscribe : https://launchpad.net/~ubuntu-phone >>> More help : https://help.launchpad.net/ListHelp >>> >> >> >> -- >> Mailing list: https://launchpad.net/~ubuntu-phone >> Post to : ubuntu-phone@lists.launchpad.net >> Unsubscribe : https://launchpad.net/~ubuntu-phone >> More help : https://help.launchpad.net/ListHelp >> > > > -- > Mailing list: https://launchpad.net/~ubuntu-phone > Post to : ubuntu-phone@lists.launchpad.net > Unsubscribe : https://launchpad.net/~ubuntu-phone > More help : https://help.launchpad.net/ListHelp >
