Default [Q] ArcS [LT18i] and Device Encryption ?

Dear Community,

I am searching for a ROM which enables device encryption on a ArcS [LT18i].

Currently I am using the Legacy Xperia ROM from the user mikeioannina which is quite cool, reliable and fast on the ArcS. Unfortunately the feature encryption is not visible nor usable on the xperia.

After browsing the Forum I did not find an answer. Meanwhile I found out most reasonable the yaffs filesystem causes this.

Due to the fact that I am working with Linux on various platforms but see myself as noob on Android and phones I have following question:

* can anybody confirm this ?
* Is it possible to change the filesystem on the ArcS for /system, /cache and /data from yaffs to ext4 ?
* if yes - how ?! Are there any pitfalls ?
* or is there a ROM already available which offers this feature on the ArcS ?

Any help is highly appreciated !

Xperia Arc and Arc S do use YAFFS filesystem. As far as I know, it is not that easy to change it to ext4 (is it possible at all?). Likely it would cause problems with the OS then too.
