Questions about var/lib/ofono/ directories

Hello ofono mailing list,

I'm wondering what ofono puts in the directory "var/lib/ofono/".

On my embedded device, I can see these directories:

  - var/lib/ofono/228014420910471
  - var/lib/ofono/228014420910471-3

The number 228014420910471 is the IMSI of my simcard right ?

In the first one (228014420910471), I can see 3 files called gprs, 
netreg and sms. And there are some configuration in it. It's pretty simple.

In the other directory, there are 4 files (4f20     6f46     6f49 
version). But I don't understand theirs purposes. Maybe these are SMS 
files ? Why the directory is named <IMSI>-3 ? Other directories with 
another number can be created ?

I'm wondering this because I want to put this directory and files in a 
separated partition of 1.3MB and put my root partition read only. So I'm 
trying to figure out if it's enough, what kind of files ofono will write 
in it, when and the frequency (it's a NOR flash partition and I would 
like to known if it's a good idea). As I understand, ofono uses this 
directory to store SMS also. But, what kind of SMS ? All the SMS I try 
to send ? All the SMS I received ? I began to read the source code but 
maybe you can tell me some hints.

Regards,
Anthony.
