And from there we’re doomed.

Could you download
<ftp://alpha.gnu.org:/gnu/guix/bootstrap/x86_64-linux/20131110/static-binaries.tar.xz>
and replace ‘gnu/packages/bootstrap/x86_64-linux/bash’ with the ‘bash’
file from that tarball (make it executable), and then try again?

I believe the problem is that these binaries date from before commit
d3b59727 (Jan. 2013), which disabled dynamic NSS support in bootstrap
binaries.

Thanks for your help!

Ludo’.
