It is my understanding that –root= option in systemctl command is used to explicitly specify an alternate root path to find the service unit files.
On RHEL/CentOS 7, the following error occurs when attempting to use the above mentioned systemctl option:
[root@server-02 system]# systemctl –root=/myservices/mds start xyz.service
Failed to get D-Bus connection: Operation not permitted
So, the idea behind the above command is that I am telling systemctl to find the service called xyz.service in the path /myservices/mds, as opposed to the default search paths like /etc/systemd/system or /run/systemd/system
Any idea why this is not working? If –root is not going to work, is there any other way to specify a custom search path?
Would really appreciate the help.
