20 # Test the 'guix pack --relocatable' using the external store, if any.
25 # 'guix pack --relocatable' requires a C compiler and libc.a, which our
26 # bootstrap binaries don't provide. To make the test relatively inexpensive,
27 # run it on the user's global store if possible, on the grounds that binaries
28 # may already be there or can be built or downloaded inexpensively.
