I wish to encrypt two external hard drives using dm-crypt/LUKS for whole-disk encryption. I want one hard drive to have an ext4 filesystem for Linux use only, and the other to have an NTFS filesystem, for possible future access from Windows, as well as Linux.
What I'm wondering is what filesystem type code should I allocate for each filesystem, given that they will be encrypted? Should the codes be as for normal filesystems, i.e. '83' for ext4 and '07' for NTFS, or are there special filesystem types used for encrypted volumes, or does it not make any difference which codes I choose?
