It is a brilliant idea to compress the content stored at the system partition which is read-only in the default setting. Such method is not new and is very common among LiveCDs. I don't understand why Asus didn't implement of such method to better utilize the small SSD space at the beginning.
The only tweak I have done after the installation are:
- Install kicker and ksmserver package for full desktop mode
- Add line "en_HK.UTF-8 UTF-8" to /etc/locale.gen, and then execute "locale-gen" to support en_HK locale
- Change the system default locale to "en_HK.UTF-8" by edit file "/etc/default/locale".
