%description
Isolated alpha build of upstream Linux 7.2 with the reviewed Xiaomi Pad 5
(nabu) hardware enablement carried from the SENEMOS 6.17 line. The selector
replaces the former 6.17 selector package during a managed Rawhide migration.
Versioned 6.17 core and modules packages remain installed as bootable fallbacks
while this kernel completes physical hardware acceptance testing.

%description -n senemos-nabu-kernel-mainline-alpha-core
Kernel image, configuration, symbol map and Xiaomi Pad 5 device tree. The
post-transaction hook regenerates only the canonical SENEMOS UKI and leaves
Android and validated fallback entries untouched.
