systemd has native kexec support. does: systemd kexec work?

"kexec -l ..." loads the kernel and the parameters "kexec -e" boots the kernel
with native systemd, the "kexec -e" step should be "systemctl kexec"
There is a third functionality of kexec. Without loading you do: kexec /boot/vmlinuz --initrd=/boot/initrd --command-line='...' and it does all the needed steps including services shutdown. And that one doesn't work with systemd. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In that case, kexec loads the specified kernel and then invokes shutdown(1). If the shutdown scripts of your Linux distribution support kexec-based rebooting, they then call kexec -e just before actually rebooting the machine. That way, the machine does a clean shutdown including all shutdown scripts. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

We might want to patch the kexec binary to know about systemd, or just the sysv compat code in systemctl. I'll check with upstream ... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Could you give me a complete test case ?
Hmm, this is interesting. I don't know what exactly I should provide. When I boot with sysvinit and do the command you do, it works. With systemd it shutdowns the system and reboots. It is an updated factory with the -next kernel. But I also tried 3.0 and 2.6.37 from kernel:11.4 and kernel:stable respectively with the same result. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
