[Announcement] support for systemd soft-reboot
Hi, systemd v254 introduced "soft-reboot" (https://manpages.opensuse.org/systemctl),which reboots the userland, but not the kernel or hardware. This allows a quick reboot after updates of e.g. dbus, glibc or openssl. With the latest snapshot, rebootmgr and os-update support this now, too. Means, if you use os-update for automatic updating your server and an update requires a reboot, but there is no new kernel or bootloader, the reboot will be done much quicker now. transactional-upate will get support for this next. The "zypp-boot-plugin" (https://manpages.opensuse.org/zypp-boot-plugin) looks at the packages which got installed or updated and decides according a config file, if: - a hard reboot is required (e.g. after update of the bootloader - kexec is enough (if only the kernel is updated) - a soft-reboot is sufficient - no reboot is necessary at all It's in the responsibility of the application triggering the reboot which of the method it used, zypp-boot-plugin only gives a hint.
