Subject: /usr/sbin/kexec: The /etc/init.d/kexec script is now missing,

Package: kexec-tools
Version: 1:2.0.29-2
Severity: normal
File: /usr/sbin/kexec
X-Debbugs-Cc: dvdkhlng@posteo.de

Hi,

the usual mode of operation of /usr/bin/kexec on Devuan (and Debian)
appears to be: load the new kernel, then trigger a shutdown.  Then at
the end of shutdown, instead of rebooting, kexec actually boots into the
new kernel.

This used to be handled by kexec's init.d hook running something like

  do_stop() {
    ...
    log_action_msg "Will now restart with kexec"
    ...
    /sbin/kexec -e
    log_failure_msg "kexec failed"
  }

instead of triggering a standard reboot.

In Devuan Excalibur (testing), all init-scripts for kexec are gone.  Now
running `kexec` just triggers a reboot, it appears `kexec -e` is never
actually executed.

Note that /usr/share/doc/kexec-tools/README.Debian still claims, that
init-scripts are installed, when in fact they are not.

I think systemd now natively includes a kexec hook for reboot, while
sysvinit-core does not, so on Devuan we still need those init hooks,
while they are gone on Debian!?
