!!! `systemctl soft-reboot` has landed! It's a userspace-only reboot: systemd shuts down as normal, but then instead of triggering a CPU reset or kexec, it pivots to a new rootfs and chainloads to systemd in that new root.
This could be kinda great for A/B immutable systems, especially because soft-reboot also supports services that persist _across_ the soft-reboot, or passing resources like server file descriptors across the reboot to minimize impact! So cool.
