Description of problem:
/etc/init/device_cio_free.conf does no longer works with systemd and needs to be rewritten. Proposed service configuration file for systemd:

[root@rtt7 ~]# cat /lib/systemd/system/device_cio_free.service
[Unit]
Description=Free all devices on startup
DefaultDependencies=no
Before=sysinit.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/sbin/device_cio_free
StandardOutput=syslog


Also one symlink needs to be created:

[root@rtt7 ~]# ls -l /etc/systemd/system/sysinit.target.wants/device_cio_free.service 
lrwxrwxrwx. 1 root root 43 Apr 26 09:56 /etc/systemd/system/sysinit.target.wants/device_cio_free.service -> /lib/systemd/system/device_cio_free.service


Tested with qeth network device and non-root DASD drive attached in /mnt/data - network was working and the DASD drive was mounted when the system finished booting.
