Hi James,
There is an iproute2 command that changes the primary,
$ ip link set dev  type bond primary 

Here's the output from the type bond help:

feature - ip link set primary ?

2016-02-04 Thread James Feeney
Should there be an

 ip link set  primary 

command in the iproute2 package, to set the Primary Slave on a "bond" type link?

It seems that the alternative now is to use the sysfs, with

 echo -n  > /sys/devices/virtual/net//bonding/primary

which, in systemd Service Unit Files, requires "/usr/bin/sh -c 'echo ...'"
rather than simply "/usr/bin/echo ...".  "ip" seems to handle all other "bond"
configuration itself.

Thanks
James
