Fix mxstartup problems

[donald]

Fix startup problem identified after the power cut reboot.

Although the error on argh was introduced by a obsolete systemctl command in /usr/bin, which was removed, there are other errors which could happen to systemctl start UNIT e.g. a misstyped service name. The results are severe (all mxstartup services get killed again) , so I still want to handle errors.

For a test you can check out this branch and run the appended script.

This goes together with a little cleanup. I've merged #5 today, so #5 is in the master, but has not been updated via bee on the distmaster. So the script contains commands to convert from the distmaster installed versions to this branch.

#! /bin/bash

if [ "$(git symbolic-ref --short HEAD)" != fix-mxstartup-problems ]; then
	echo "Please checkout fix-mxstartup-problems"
	exit 1
fi

systemctl disable mxstartup-systemd.service
rm /etc/systemd/system/mxstartup-systemd.service
rm /usr/sbin/mxstartup.systemd

systemctl disable mxstartup-mxvip.service
rm /etc/systemd/system/mxstartup-mxvip.service

systemctl disable mxstartup-classic.service
rm /etc/systemd/system/mxstartup-classic.service

make install
systemctl enable mxstartup.service

systemctl daemon-reload

echo ""
echo "***************"
echo "On-disk changes done. For test reboot or ..."
echo ""
echo "  systemctl stop  mxstartup-mxvip mxstartup-classic "
echo "  systemctl start mxstartup"
