[Bug 1227520] Re: Timezone changes are not working due to ro /etc and bind mounts

[Martin Pitt]

So, to summarize my understanding what should happen (sorry, I'm still
quite new to that touch layout, so I rather make sure):

 * livecd-rootfs creates /etc/writable/ (use a generic name as we might need it for other cases, and please no dotfiles)
 * livecd-rootfs moves /etc/localtime to /etc/writable/localtime and adds a corresponding symlink
 * lxc-android-config declares /etc/writable as writable  -> this would create a mount point, and hide the original contents of /etc/writable/ as created by livecd-rootfs; how does the mounted file system get /etc/writable/zoneinfo? Is that done magically by the "transition" flag in /etc/system-image/writable-paths?
 * timedated and tzdata's postinst check if /etc/localtime point to /etc/writable (i. e. not to /usr/share/zoneinfo) and do its operation on the symlink target instead as a fallback.
