Hi all,
I am doing some tests with a CentOS7 vm image before to enter in our production environment. I need to migrate some sysvinit scripts to systemctl.
In all of them I need to launch some daemons in the same init script. For example:
a) start daemon1 b) if daemon1 returns no startup errors, launch daemon2 c) if daemon1 returns any startup error, doesn't start daemon2 and exit.
Is it possible to do this with systemctl??
Thanks.
Could this help?

ExecStartPre=, ExecStartPost=
Additional commands that are executed before or after the command in ExecStart=, respectively. Syntax is the same as for ExecStart=, except that multiple command lines are allowed and the commands are executed one after the other, serially.
If any of those commands (not prefixed with "-") fail, the rest are not executed and the unit is considered failed.
