Historically Desktop / Server, only configured LUKS full disk encryption with an LVM layer. Thus ones root ext4 filesystem was an LVM volume, on an VG group, on LUKS, on a GPT partition.
The upcoming Ubuntu Core 20 has full disk encryption with TPM support. In that configuration ext4 filesystem is created directly on the LUKS volume which is directly on a GPT partitition.
For the upcoming HH 21.04 release, I want to change Desktop/Server, to also install in a similar fashion. Specifically such that by default, we simply use ext4+LUKS without LVM.
It seems to me that despite having LVM layer, it’s not actually used or appreciated much.
Would you be ok with having full-disk encryption without LVM by default?
