This was noticed on a GUI install (I do not remember seeing this on a TUI install).
When "Select Individual Packages" is performed, the display presented has TWO
"System Environment" selections. This first has a "Base" selection which is
empty. The second is the correct one with a "Base" and other entries plus packages.
Something is specspo-unhappy.
That something was hwdata, and had a misspelled "Environment" part ("Enivroment").
This was fixed a couple of days ago.
It's in base, and packages in base aren't shown...
(fix is in specspo-7.2.92-3)
