Re: error: Unable to start server (community 3.18.0)

I checked an install of community on centos-7 and it would seem that the 
package is not corrupt but that somehow your cf-execd.service file did 
become corrupt.

```
cf-remote spawn --platform centos-7-x64 --count 1 --role client --name cent7
cf-remote --version 3.18.0 install --edition community --clients cent7
```

I bootstrap and seem to have no issues.

```
# grep cf-server /var/log/messages
...
Jul  8 14:15:58 ip-172-31-18-118 cf-serverd: notice: Server is starting...
Jul  8 14:15:58 ip-172-31-18-118 cf-serverd[11219]: CFEngine(server)  
Server is starting...
```

Can you include the text of your cf-execd.service file?

Thanks,
Craig
