This could be done with something like:
diff --git a/gnu/system.scm b/gnu/system.scm
index 01baa248a2..3ff3073017 100644
--- a/gnu/system.scm
+++ b/gnu/system.scm

(packages operating-system-packages ; list of (PACKAGE OUTPUT...)
- (default %base-packages)) ; or just PACKAGE
+ (thunked) ; or just PACKAGE
+ (default (append (file-system-packages
+ (operating-system-file-systems
+ this-operating-system))
+ %base-packages)))
(timezone operating-system-timezone) ; string
(locale operating-system-locale ; string
However, this would only work for the default values of ‘packages’. In
other cases, users would have to add (file-system-packages …) explicitly
by themselves, which is not great.
Alternately, we could turn ‘%base-packages’ into a macro that expands
to something like:
(gimme-the-base-packages this-operating-system)
but that wouldn’t be great because now you’d be unable to refer to
‘%base-packages’ like a regular variable, outside the lexical context of
an ‘operating-system’ form.
Thoughts?
