Does ext4-formatted microsd card work out-of-the box already?

Hi,
I'd like to reformat my 64gb microsd card from fat32 to ext4. This is due to fat32 file naming restrictions giving me problems. When I copy files from my music library to the sdcard, some of the files have characters which fat32 does not allow and I'd have to first find all of them and then change these manually.
I'd like to know does Jolla already fully support and automatically mount sdcards formatted to ext4 or would I still need to create shell scripts such as on this topic? https://together.jolla.com/question/2769/why-doesnt-a-sd-card-work/
I'd love for ext4 to be mounted and recognized out-of-the box. If a workaround is still needed, I'd like to ask Jolla to include it in their next Sailfish update.
It is not recommended to use a journaling FS on flash storage.

So far it works just fine, afaict. btrfs is said to have autodetection whether it is on flash-based storage, to which it adjusts automatically. For now I'm not worried.
Fuzzillogic ( 2014-04-06 16:44:52 +0200 )edit@vasavr - isn't journaling optional when using ext4 ?
But yes Btrfs would be the obvious choice ..
