Hi everyone!

I wrote a dracut module a couple of weeks ago which runs during pre-mount
basically performs this steps:
- If >99% of disk capacity is partitioned, exit.
- else, expand the partition to full disk without losing data.

I'm attaching a tar.gz file, without the extension becasue gmail doesn't
like it.

I've tested it only with XOs 1.5 and haven't measured time cost.

If someone else is going to test it, please send comments, bugs or
