## Motivation

Can we enable SLAAC support in all our salt managed machines regardless if the infrastructure needs/supports this?
## Acceptance criteria
* **AC1:** Machines in PRG2e configured by salt, like ada, get full IPv6
* **AC2:** Machines in PRG2 configured by salt, like worker29, *still have full IPv6
## Suggestions
* Check differences between openqaw5-xen which already has IPv6 and ada which does not. Maybe ada has IPv6 explicitly disabled by sysctl.
* If ada is not just a single exception then add to salt
```
# cat /etc/sysctl.d/10-slaac.conf
net.ipv6.conf.default.use_tempaddr=1
net.ipv6.conf.default.autoconf=1
```
and see if that automagically fixes IPv6 on ada and does not break something on others. If that does not work then set
```
BOOTPROTO="dhcp4+auto6"
```
but possibly only for machines in PRG2e, not PRG2, or based on salt grain or something
