Ok new proposal:

* introduce container.workDirectory in xwiki.properties

+1. Not sure getWorkDirectory is the best name, though. It doesn't
contrast enough with getTemporaryDirectory, especially since
getTemporaryDirectory usually returns something called "work".
The meaning of the function is: get me a directory where I can safely
write some data that will be available after restarts (best effort). By
the way, it should be mentioned in the javadoc that there's no hard
guarantee that the data won't be removed between restarts.
Some proposals:
- getPermanentDataDirectory
- getPermanentStorageDirectory
- getSafeStorageDirectory
- getDataStorageDirectory
- getDataDirectory
- getWorkDataDirectory
I think my slightly favorite is getPermanentDataDirectory.
I would really like to start using the API and I
don't really care how
it's implemented at EM level as long as I get a persisting folder when
I can write stuff. We can always add more fallbacks before
getTemporaryDirectory() later.
WDYT ?
Here is my +1
