Read only file system in Debian 9

[alterfritz]

Hi,

1st - thanks for your wonderful job. I really like using Armbian. 

 

I have setup a few small nanopi neo's with spotify / airplay / Bluetooth to play music via Echo-Dots with line in connected speakers. 

 

Now I would like to make this setup as stable as it can be., so I was thinking about making those SD cards read only.

 

What I got from here - on the old kernel 3.4 there is an option - apt-get install overlayroot.

 

Sadly I'm on the latest Debain based image -

 

fritz@nanopineo2:~$ uname -a
Linux nanopineo2 4.14.18-sunxi #24 SMP Fri Feb 9 16:24:32 CET 2018 armv7l GNU/Linux
 

unionfs-fuse is maybe a good option. Before I try that out myself - anybody had done this?

 

Any guide I can use / follow?

 

Regards

Joerg

Hmmm... seems not to be easy doable. I guess moving to Armbian Xenial is maybe an easier option. Thoughts?

IMO the best way would be to study overlayroot scripts for Ubuntu and make them work on Debian.

Hi alterfritz,

did you make any progress on this, yet?

I am searching for a similar solution: something like overlayroot for Armbian_5.65 for a BananaPi M2+ (Debian_stretch_next_4.14.78).

The overlayroot package that is mentioned in this thread (1st reply):

would be just what I would need, but the "overlayroot"

package doesn't seem to be available for Debian Stretch.

So, before starting to botch something together myself, I would like to know, if you have found a good solution already.
