Re: IOCs under procServ as system services under systemd?

[Niklas Claesson <niklas.claesson@cosylab.com>]

I do, but it is a bit special since I automatically create services based on the contents of a directory. 

I have a service template that looks like this (will create one service per IOC): 

```
​[Unit]
Description=IOC: %I
After=rc-local.service

[Service]
User=ioc

# Only execute IOC if st.cmd exists
AssertPathExists=/opt/startup/ioc/%H/%i/st.cmd

# Execute StartPre with root permissions
PermissionsStartOnly=true
ExecStartPre=/bin/mkdir -p /var/log/procServ
ExecStartPre=/bin/chown -R ioc:ioc /var/log/procServ
ExecStartPre=/bin/mkdir -p /var/run/procServ/%i
ExecStartPre=/bin/chown -R ioc:ioc /var/run/procServ/%i
EnvironmentFile=/opt/startup/ioc/%H/%i/env.sh

# Run procServ with user ioc
ExecStart=/usr/bin/procServ --allow -f -L /var/log/procServ/out-%i -i ^C^D -c /var/run/procServ/%i ${PROCSERV_PORT} ${EPICS_MODULES_PATH}/environment/${ENVIRONMENT_VERSION}/${BASE}/bin/${EPICS_HOST_ARCH}/iocsh /opt/startup/ioc/%H/%i/st.cmd -n %i

[Install]
WantedBy=multi-user.target
```

and then I have a "master" service which creates all the IOC services:

```
[Unit]
Description=IOC Starter
After=ess-boot.service

[Service]
Type=oneshot
ExecStart=/bin/sh -c 'for i in /opt/startup/ioc/%H/*; do /bin/systemctl start ioc@$${i##*/}.service; done'
```
