The Subiquity diskful path builds three values from configuration, and nothing checks that the value it builds is one the consumer can use. The boot flip addresses port 3002. xcatd's install monitor listens on site.xcatiport, so a cluster that moves the port loses the flip and every node PXE-loops. The exchange also counts any reply as an accepted request, so a different service on that port reads as a flipped node. xcatd greets with "ready" and answers every request with "done". subiquity_nfsroot_server resolves the install server without a family. A dual-stack management node answers with its IPv6 address, and nfsroot=<v6>:<path> is unparseable, because klibc nfsmount takes everything after the first colon as the path. The DNS setup writes the xcatmaster name as a nameserver when getent fails, which is the case the step exists to prevent. ubuntu_subiquity_boot_flip.t drives the template's own late-command against a stand-in monitor. ubuntu_resolvconf_ip.t runs the DNS step and reads the file it writes. debian_subiquity_boot_params.t drives the helpers with a dual-stack resolver. All three fail on this commit. Signed-off-by: Daniel Hilst <392820+dhilst@users.noreply.github.com>

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
