Can someone explain to me the default partitioning scheme of an encrypted-full disk install of Ubuntu 19.04, or rather, the names of the partitions? During install I chose to erase, and install using the full disk, and also chose encryption. I checked the partitions after installation,and it shows this: It shows three partitions. Gparted shows sda1 as a EFI partition, but I'm not sure what sda2 partition is. Is it a boot partition? It looks like basically all of Ubuntu, sda3, is encrypted. I guess my main concern is, what's not encrypted?
Your operating system is installed on disk
This disk has three partitions:
sda2 are partitions that are needed for the system to boot up.
sda1 is your EFI system partition (ESP).
/boot. The data on these partitions is not encrypted.
sda3 is an encrypted partition. Once you have supplied your password to unlock this partition, there are two more partitions inside: your root (
/) partition and also a swap partition. All of the contents of
sda3 are encrypted.
