/tmp is a sticky directory. When the OS is configured with fs.protected_regular=1, this means that O_CREATE open is forbidden for files in /tmp if the calling user is not owner of the file, except if the file is owned by the owner of the directory. The installer (executed as root) currently creates a file in /tmp, then modifies its owner to pkiuser and finally writes the pki config in the file. With fs.protected_regular=1, the write is denied because root is not owner of the file at this point. The fix performs the ownership change after the file has been written.
