ipv6-support
A map of ssh public keys to install for the root user
In some installers and setup environments, it is desirable to selectively
turn on or off IPv6 support. The value of this Param (true or false)
can be used in automation code to effect the appropriate settings change.
In the case of Ubuntu 20.04 and newer, it is used in the autoinstall subiquity generated configs to selectively disable IPv6. If the install environment doesn't support it, then the the network interface will flap many times during package install, generating STDOUT and STDERR messages.
The default value of this Param is set to false (disable IPv6) for those
places in code that use this setting. Settings definitions:
true: ENABLE IPv6 support where the Param is being usedfalse: DISABLE IPv6 support where the Param is being used
