LOAD_KEXEC=true
With LOAD_KEXEC=true, the intent always has been for "reboot" and
"systemctl reboot" to do a kexec reboot. That functionality has broken
off and on over the last 3 years as new versions of systemd were
released. I have now removed LOAD_KEXEC support because of it not being
reliable due to changes happening in systemd.
So I would say "reboot" and "systemctl reboot" doing a kexec reboot with
"LOAD_KEXEC=true" is expected behavior. If you are ok with it, I would
like to close this bug.
Thanks,

note that this is from a copy of the file I made yesterday, since then
I upgrade to the unstable kexec-tools.
I can confirm that this bug is not there with the unstable version
1:2.0.27-1 (as the initscripts are no more this was expected).
debconf entry:
* kexec-tools/load_kexec: true

Dear Maintainer,
When I call "reboot" or "systemctl reboot" I ends up with a kexec
reboot.
I expect a cold reboot.
What is the value for LOAD_KEXEC in /etc/default/kexec?

I have enabled kexec-tools as it is a dependency of kdump-tools.
I supposed enabling a kexec kernel was a requirement to get kdump
tools
to dump to /var/crash. Maybe I misunderstood.
In the journal I get after systemd telling it is rebooting:
"

reboot now!

This even though the kexec-tools Debian REAME tells:
/usr/share/doc/kexec-tools/README.Debian
"reboot" command with ystemd will by default do a cold reboot. To
kexec
a new kernel with systemd, use "systemctl kexec".
I believe this is a new issue maybe from my upgrade in June of
kexec-tools
from 1:2.0.20-2.1, 1:2.0.25-3+b1.
That is I did not change my kexec-tools config and I believe
monthes ago
systemctl reboot gave me a cold reboot, not a kexec one.
Note that it does not means the setup was fine beforehand as I do
not
have a single kdump crash file in /var/crash.
I do not know if kexec reboot was even working with the previous
version. Now it kexec reboots fine ... but even when I ask
systemctl for
a default coldreboot.
I don't believe this affects unstable as kexec-tools 1:2.0.27-1
removed the
initscripts that are called by systemd at reboot.
Maybe this is expected behavior with systemd-sysv installed?
Cheers,
Alban
