* a multi-homed host which needs to set rp_filter to 0 (which is set to 1 on ubuntu by default)
* no way to do this other than by setting sysctls
* for bare-metal hosts & MAAS this can be done via curtin
* for LXD containers this is not possible (one would use this in manual setups https://github.com/lxc/lxd/blob/master/doc/cloud-init.md)
