Comment 20 for bug 1227520

livecd-rootfs changes pushed to http://bazaar.launchpad.net/~ubuntu-core-dev/livecd-rootfs/trunk/revision/848
writable-paths changes pushed to http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/saucy/lxc-android-config/saucy/revision/102

I tested those by

 * making image writable
 * umounting /etc/{adjtime,localtime,timezone}
 * Running the new live-build/ubuntu-touch/hooks/03-etc-writable.chroot script
 * Replacing /etc/system-image/writable-paths with the new version from above branch
 * making image non-writable again, reboot

Now I have

$ ls -l /etc/{adjtime,localtime,timezone}
lrwxrwxrwx 1 root root 21 Sep 25 09:22 /etc/adjtime -> /etc/writable/adjtime
lrwxrwxrwx 1 root root 23 Sep 25 09:22 /etc/localtime -> /etc/writable/localtime
lrwxrwxrwx 1 root root 22 Sep 25 09:22 /etc/timezone -> /etc/writable/timezone

and I can create new files in /etc/writable/. So I'm fairly sure that this is ok, but peer review highly appreciated before I actually upload this. Also, I believe Oliver needs to add that to some google docs to get a "change request".
