Is there a possibility to make make Ubuntu MX4 phone to beep (make a sound for less then 1s) every hour?
Why do I need it? I used to have my watch which beeps every hour and I would like to have such possibility on my phone too.

The installation of emacs is possible with the following commands:
sudo su
mount -o remount,rw /
apt-get install emacs
You need a passphrase or a number code for your phone and you need to install the com.ubuntu.terminal-app to input these commands.
Emacs is also started from com.ubuntu.terminal.
Specification of my phone: BQ Aquaris E5 Ubuntu-Edition
# uname -a
Linux ubuntu-phablet 3.4.67 #1 SMP PREEMPT Fri May 29 10:43:18 UTC 2015 8e13c5f armv7l armv7l armv7l GNU/Linux
Attention: As far as I understand what I read before, updating the phone via GUI is no longer possible after that.
Currently, I am asking here whether updating via apt-get is a full replacement.
I am using the following configuration file ~/.config/com.ubuntu.terminal/Layouts/emacs.json for working with emacs using the built-in virtual keyboard.
This configuration is far from ideal. I posted it here, since it is difficult to start without any emacs-adapted soft-keyboard on the console.

We can use /lib/init/fstab. But before we should set a system partition as writable:
sudo android-gadget-service enable writable
After rebooting we can edit /lib/init/fstab with sudo nano or sudo vim, for example we can add this string:
/dev/mmcblk1p2 /home/phablet/mnt/sd ext2 defaults,noatime,nodiratime,errors=remount-ro 0 2
to mount ext2 partition on sd card. Then, we make system partition read-only again: sudo rm /userdata/.writable_image and reboot.
Of course, after getting new OTA we should repeat it again.
Standard /etc/fstab is mystical in ubuntu-touch, mounting (binding) to tmpfs and seems is generated on-the-fly or just in starting. But /lib/init/fstab works well.

Until there is a true background tasks/triggers/etc. API in Ubuntu itself this is probably not possible. It might hypothetically doable by creating a service that generates a push notification every hour and make your phone beep when it receives it, but I'm not sure if it is possible without adding a custom online account to the system image. Anyway it is kinda crazy idea and would be nothing more then a just-because-I-can solution.
