In order to take advantage of all the features of systemd under Debian jessie I consulted many websites, but I have not found answers to my questions: How to set systemd as the default service manager under debian jessie? Do we get a stable system after  performing this operation?
How to set systemd as the default service manager under debian jessie?
linux;debian;systemd
systemd is the default init system in Jessie, even when upgrading. If you want to enforce this, make sure the systemd-sysv package is installed; if that changes anything, reboot, and you'll see that the first process is /lib/systemd/systemd --system:ps -f -p 1Once that's done, you'll get full use of systemctl, journalctl etc. Since systemd is the officially-supported default in Jessie, you can expect the usual stability.Other components of systemd are being introduced for Stretch, and are not available for Jessie; see for example systemd-coredump.
