# This file evaluates to a function that, when supplied with a system
|
|
# identifier, returns the set of all packages provided by the Nix
|
|
# Package Collection. It does this by supplying
|
|
# `all-packages-generic.nix' with a standard build environment.
|
|
#
|
|
# On Linux systems, the standard build environment consists of
|
|
# Nix-built instances glibc and the `standard' Unix tools, i.e., the
|
|
# Posix utilities, the GNU C compiler, and so on. On other systems,
|
|
# we use the native C library.
