I agree this is annoying, but I would expect distros to leave
this set to 1 (for backwards compatibility with scripts that "modprobe
bonding" then assume bond0 exists). This leaves the problem in place
for the vast majority of users.
Is there a reasonable way to resolve this that would actually
fix things for regular distro kernel users?
