systemd soft reboot I wanted write about a brand new feature in systemd 254 that has got me very excited, this feature is soft reboot which is described as: systemd-soft-reboot.service is a system service that is pulled in by soft-reboot.target and is responsible for performing a userspace-only reboot operation. When invoked, it will send the SIGTERM signal to any processes left running (but does not follow up with SIGKILL, and does not wait for the processes to exit).
