From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It depends on where the encryption data is stored. If the bootloader and bios/efi are locked down and the data to unlock is stored in an encrypted enclave or one is using a TPM (and not an external chip one that can be sniffed with a pi), that's a reasonable protection for the OS even if somebody gains physical access.
You could also store the password in the EFI, or on a USB stick etc. It doesn't help you much against longer-term physical access but it can help if somebody just grabs the drive. It's also useful to protect the drive if it's being disposed of as the crypto is tied to other hardware.
Even just encrypting the main OS with the keys in the boot/initrd has benefit, as ensuring that part is well-wiped makes asset disposal safe(r). Some motherboards have an on-board SDCard or USB slot which your can use for the boot partition. It means I don't have to take a drill to my drives before I dispose of them
