The single flat xcat-core repo serves el8/el9/el10 from one build, but two spec
decisions were resolved at BUILD time and so were wrong for the other ELs that
share the same repo.
1. DHCP backend. xCAT.spec and xCATsn.spec selected the dhcp provider with a
build-time %if (rhel >= 10 -> kea, else dhcpd), so an el10 build wrongly
required kea on el8/el9 (and an el8/el9 build wrongly required dhcpd on
el10). Replace it with an install-time RPM rich dependency:
Requires: (kea if (system-release >= 10) else /usr/sbin/dhcpd)
Requires: (kea-hooks if (system-release >= 10))
dnf now resolves it per client: kea on el10+ (which dropped ISC dhcp from the
distro), dhcpd on el8/el9. SLES has no "system-release" provide, so the
condition is false there and it falls back to /usr/sbin/dhcpd, preserving
prior behavior. system-release is versioned per release package
(el10=10.x, el9=9.x, el8=8.x).
2. openssl. Make the xCAT-server openssl Requires uniform across EL (non-SUSE)
instead of el10-only, so the produced package set does not depend on which EL
the build host happened to be.
Also drop xCAT-genesis-base from the default @PACKAGES set in buildrpms.pl: its
initramfs bundles the build-chroot kernel/glibc and is therefore OS- and
arch-dependent, so it cannot ship in the single flat core. It is now built per
target by the xcat-dep pipeline (mockbuild-all.pl, via
`buildrpms.pl --package xCAT-genesis-base`) and ships in xcat-dep/rh<N>. The
explicit `--package xCAT-genesis-base` build path is retained.

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
