[Discuss] Rsync "one file system"

[jbk at kjkelra.com (jbk)]

I was cloning a fedora31 system to another partition using 
rsync using the -x option to restrict decent to one file 
system, at least that was what I thought, but the contents 
below the mount point were copied anyway.

rsync -ax bin boot data (<- mounted to separate partition) 
... <destination>

So what am I not understanding?

Typically when I want to copy the top level directories I 
use the command syntax:

rsync -dogp proc sys srv ...... <destination>

The mounted partition are per the rules in fstab.

So if someone can enlighten me I'd appreciate your comments
