Enabling MAC randomization

[nielsbasjes]

Hi,

I have installed Ubuntu Touch on a FairPhone 5.
I would like to configure MAC randomization on the WIFI connection.
I have not been able to find this as a setting in the config app.

The normal way of doing this with the NetworkManager is by setting these kinds of properties in the config files

wifi.scan-rand-mac-address=yes
wifi.cloned-mac-address=random

What I found on my phone is that apparently the /etc/NetworkManager.conf and /etc/NetworkManager/conf.d are all on a readonly file system.
The /etc/NetworkManager/system-connections is explicitly mounted on a special directory which is writable.

So far I have only come up with these steps, but they seem to me like too much of a hack.

• Adding an extra conf.d directory in a writable location (next to the place where the /etc/NetworkManager/system-connections is mounted)
• Copy all files that are already in there to the new location
• Add an extra mount line in the /etc/fstab
• Mount it
• Add a new config with the above mentioned lines.

My question is simple: What is the proper way to enable MAC randomization on Ubuntu Touch? Or is the above mentioned way the best available solution?
