Are these suitable for flash cards? IMHO such a project is not completed.

Warning:
A journalling filesystems suffers often simply from application design:
If your application deletes a file on disk and after that writing the new file
(e.g. configuration file) and between these 2 atomic transaction the power fails
it's perfectly in spec that the original-file is lost.

Not sure how vdr and it's plugins perform here, but i had such problems with
kde-config files.

Journalling-FS can also be "rolled back" if the logs are still available but
i'am not sure if that is what one wants in such a situation - i want my file
there a reboot time - so better have a look at such (regularly rewritten) files.
