[systemd-devel] Binary launched in ExecStartPre gets killed...

[Belal, Awais]

Hi,

I have a unit file which does something like this:
In ExecStartPre -> Start A
In ExecStart -> Start B

Now the thing is B depends on A to function correctly and A is a binary itself. The behavior I am seeing is a little obvious but still I thought there might be a way around this. When the unit is started A is launched correctly but then after some time it gets killed with a term signal 15 and this happens before B is started and hence when B is launched it fails. Here's what my unit file looks like...

[Unit]
Description=B
After=xyz.service

[Service]
EnvironmentFile=-/tmp/my.env
ExecStartPre=/bin/sh -c 'echo "ADDRESS=`A --print-path`" > /tmp/my.env'
ExecStart=/usr/bin/B

[Install]
WantedBy=graphical.target

Any suggestions here would be highly appreciated.

BR,
Awais
