Some parts of IPA requires IPv6 stack to be enabled in kernel (replica conncheck, AD trusts, ...).
Before a server/replica installation, a check should be performed to verify IPv6 stack is enabled. If it is not, installation should be aborted with an error message stating that IPv6 stack has to be enabled. The message may also point out how to correctly disable IPv6 addresses from interfaces without turning off IPv6 stack.
We should also consider checking if IPv6 stack is enabled when starting ipactl services.
On a system with IPv6 stack enabled, the following entry is present. On systems with IPv6 disabled, it is not present:
/proc/net/if_inet6
