The D in Systemd is for Directories: Poettering says his creation will phone /home in future
Systemd inventor Lennart Poettering told the crowds at the All Systems Go Linux user-space event in Berlin he intends to reinvent home directories to fix issues with the current model that are otherwise insoluble.
He is also much concerned with a security issue, which is that even when full-disk encryption is in use, when the system is suspended the decryption key is held in memory, so that if a laptop is stolen while suspended it would be possible to access the data.
A person at the session asked what should be done by a university student, for example, who wanted to log in to a Linux machine that was rebooted overnight from 200 miles away. The answer: "If you really want that this system can come up on its own, don't use this stuff. This is about security."
