It's not the argument anyone else is going to make, but as an example... the last time I checked, ecryptfs had been rendered nonfunctional in Debian Buster because the current revision of systemd had made changes that made ecryptfs nonfunctional. Supposedly they're going to have a solution in systemd that'll be of equivalent functionality, but in the meantime, in debian, you're stuck with the systemd stack and not using software that systemd renders nonfunctional. So I had to back up, reinstall and encrypt the whole hard drive, including swap space, because that's how debian installers do it...
