I suppose this is Guix 0.8.2 on top of another distribution, right?  Did
you install from source or from the binary tarball?  Did you enable
substitutes (info "(guix) Substitutes")?

I just rebuilt it on my laptop (on GuixSD) and
/gnu/store/hs7ldmg9ix8irdw5gj4vr55ml8m08723-tar-1.28 (x86_64-linux)
builds fine; same on Hydra.

Sounds like ‘bar’ is expected to be removed but is not.

Same story here.

I don’t fully understand the tests, but they seem to be testing a
deterministic property.

Now, there are several tests creating files/directories call ‘bar’; they
may run in parallel, and it’s not clear to me whether or not they’re
using separate directories.

Does the build succeed if you run it another time with:

  guix build tar -K -c 1

Thanks in advance,
Ludo’.
