Well, what am I supposed to do? The socket (or what it was) needs to be put somewhere, and IIRC, it wasn´t my choice to put it there but is a default.

I am confused why you would want persistence for these objects in any operating system. Could you show us the relevant errors you are getting when rebooting?

You mentioned SELinux. Is the problem that you have SELinux enabled and the packages that you are using do not come with an appropriate SELinux policy making them unable to open sockets / write pid files? Which SELinux context are these applications running in?
