getipaddr answers from %::hostiphash before it resolves. The bypass tests OnlyV6 and GetAllAddresses and does not test OnlyV4, so a caller that asks for IPv4 is handed whatever the first lookup cached. An unrestricted lookup passes AF_UNSPEC to getaddrinfo, so on a dual-stack management node with an AAAA record it caches the IPv6 address. xcatd is long-lived and the hash is a global, so one earlier caller poisons every OnlyV4 caller after it. debian.pm then writes nfsroot=2001:db8::1:/install, which is not a parseable nfsroot, and the Subiquity install never mounts. dhcp.pm and mknb.pm hold four more OnlyV4 callers with the same exposure. The test also pins what the fix must not break: an IPv4 cache entry is still served to an OnlyV4 caller, and an unrestricted caller still gets its cache hit whatever family it holds.

xCAT
xCAT is a toolkit for deployment and administration of clusters of all sizes.
The xCAT sunset was only a quick eclipse
Dear xCAT Community,
The xCAT sunset has changed course. VersatusHPC has been invited to join the xCAT Consortium, and future development will move toward direct upstream contributions coordinated with the Consortium and its existing member companies.
That matters most for Enterprise Linux 10 (EL10). EL10 support is coming to xCAT, restoring a future operating-system path for sites that still rely on xCAT. This is an important change from the previous sunset guidance, where the lack of an EL10 path was one of the strongest reasons to move away from xCAT.
The xCAT Consortium continues to recommend Confluent as the long-term successor to xCAT, and that remains the Consortium position. Users planning new cluster-management deployments should evaluate Confluent and its xCAT comparison documentation.
At the same time, xCAT is no longer sunsetted. The Consortium and participating companies will continue updating xCAT while there is community and user demand for it.
In summary:
- xCAT development is continuing upstream through the Consortium and participating companies.
- Enterprise Linux 10 support is coming.
- Confluent remains the Consortium-recommended successor and migration path.
- xCAT updates will continue while there is community and user demand.
We want to thank the xCAT Consortium and community for keeping this project moving. The sun went behind the moon for a moment, but xCAT is still here.
For more information on Confluent and how to get started, please visit the Confluent: Project Page, Documentation or Confluent vs xCAT comparison.
With thanks,
The xCAT Consortium
