The future is actually yesterday.  :-)

It’s a bit trickier.  linux-libre-headers is propagated by glibc, so if
you install glibc, you get both.

However, glibc is an /implicit/ input of everything that uses
‘gnu-build-system’, such as libgcrypt.  So it doesn’t get installed when
you install libgcrypt.

I’m not sure whether glibc should be automatically installed as if it
were a propagated input.  If the answer were “yes”, I’m not sure how to
achieve it elegantly, because implicit inputs are hidden, by definition.

Thoughts?
