Nothing, it works as expected. It is not fixed offset but req. alignment. Using --align-payload=1024 means alignment to the nearest 512KiB boundary, because the keyslots space requires more than 512KiB it aligns to next multiple of it - i.e. 2048 sectors. If you increase key size (thus keyslots size), it will probably switch to to 3072 etc. Milan _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
