Daniel Hilst 05fc81f7b5 fix(subiquity): three values the Ubuntu install path accepts and cannot use
The boot flip in compute.subiquity.tmpl addressed 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 back into the installer. The flip now reads
site.xcatiport and keeps 3002 as the default. TABLEBLANKOKAY, because the key is
optional and a plain TABLE lookup of an absent key fails the whole template.

The flip also counted any reply as an accepted request. It now requires the
monitor's "ready" greeting before it sends "next", and "done" afterwards, so a
different service on that port is not read as a flipped node.

subiquity_nfsroot_server in debian.pm called getipaddr without a family. A
dual-stack management node answers with its IPv6 address, and casper takes
everything after the first colon in nfsroot= as the path, so the live filesystem
never mounts. It now asks for IPv4, as dhcp.pm and mknb.pm do.

The DNS setup wrote the xcatmaster name as a nameserver when getent found no
address, which is the case the step exists to prevent. It now keeps the
resolv.conf DHCP gave the live installer.

ubuntu_subiquity_boot_flip.t, debian_subiquity_boot_params.t and
ubuntu_resolvconf_ip.t fail on the parent commit and pass here.

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
