bug#27032: make check fails for Guix 0.13.0

Hi William,

There was one problem, which is that substitutes for the ‘guix’ package
itself were missing.  This is now fixed, meaning that if you install
GuixSD 0.13.0 now, you won’t have to build ‘guix’.

Could you try again?

I’m surprised by the “dtmp” prefix here.   It should be
“/tmp/guix-tests”.  Was the log altered in some way?

Apart from that it’s hard to draw any conclusions.  We run these tests
very often without problems.  The difference here is that the GuixSD
installation system uses unionfs-fuse for its root file system, and I
suspect that file system could have slightly different semantics that
bite here.  We’ll have to investigate this.

Thanks for your report!
