The bootstrap binaries currently consist of statically-linked
executables for 'bash', 'tar', 'xz', and 'mkdir', which are included in
the Guix source tree in the gnu/packages/bootstrap/ directory:

and also a few additional tarballs of statically-linked binaries
downloaded from:

which includes guile, gcc, binutils, glibc, and a "static-binaries"
tarball with coreutils, tar, gzip, bzip2, xz, patch, sed, grep, and

These bootstrap binaries were generated by the code in
gnu/packages/make-bootstrap.scm in the past, and are rarely changed.
They are fetched/imported into the store by code in

The current bootstrap binaries for x86_64-linux and i686-linux were
generated in November 2013, although there is ongoing work to replace
these with a reduced set of bootstrap binaries:

It is likely that our 'master' branch will be based on these reduced
bootstrap tarballs, or similar ones, within a few months.
