You can't have it all ;-)
I see several options.
- use 2001:db8:38a5:8:0:0:0:2006/48/eth1
- abandon haresource
- hack the "ResourceManager" script of heartbeat,
allow for "escaping", or special case IPv6addr or similar...
it's plain shell after all
- hack the resource.d/IPv6addr *wrapper* script only,
to mangle the input parameters.
The last two options would look something like below.
You need only *one* of these, though using both would not hurt.
Untested, and likely whitespace mangled ;-)
