Ubuntu for many years has allowed EXT4 file-system encryption when making use of LVM management but for Ubuntu 21.04 it's looking to offer the file-system encryption without having to go through LVM.

An early proposal by Ubuntu/Canonical developer Dimitri John Ledkov is proposing full disk encryption by default without LVM. With Ubuntu Core 20 there is going to be support for TPM-backed full disk encryption created directly on the LUKS volume and in turn directly on a GPT partition without LVM. For Ubuntu 21.04, the developers are looking at changing the Ubuntu desktop/server installers to potentially allow similar EXT4 encryption directly atop LUKS without LVM.

The basis for the default change seems to be, " It seems to me that despite having LVM layer, it’s not actually used or appreciated much. "

Thus there is a request for comments on this possible change for Ubuntu 21.04.
