At the All Systems Go conference in Berlin 20-22 September, Lennart Poettering proposed a new extension to systemd, systemd-homed.service. A video of his session can be downloaded from media.ccc.de with accompanying slides [PDF].
In his presentation, Poettering outlines a number of problems he sees with the current system, like /etc needs to be writeable, UIDs need to be consistent across systems, and lack of encryption and resource management.
His goals with the proposed solution are migrateable and self-contained, UID-independent home directories with extensible user records that unify the user's password and encryption key; LUKS locking on system suspend; and Yubikey support.
He identifies a number of problems this new idea could cause with SSH logins, disk space assignments, UID assignments, and LUKS locking.
He plans to introduce JSON user records that can be queried via a Varlink interface and to a certain extent are convertible to and from existing formats. The home directories will be stored as LUKS-encrypted files that will be managed by the proposed new service, systemd-homed.service. The system integration will be supported by pam_systemd and systemd-logind.service.
It will be interesting to see how the world responds to this new take on systemd's ever-increasing encroachment of Linux.

On my part, it's because the situation as a user is using a distro that either relies on systemd *or* has a large reasonably-current repo, in part because far too many programs rely on a library that's somehow tied to systemd and are therefore a huge PITA (or impossible) for distro devs to package and/or for users on non-systemd distros to compile.
