Guix,

I ran into the following running ‘guix pull’ from the 0.16.0 
aarch64 binary tarball on the original Overdrive OpenSUSE.

Apologies for the truncation, but this happened over the serial 
console.  I'm running ‘guix pull’ with output redirection now, and 
it's been running for a suspiciously long time without errors…

Kind regards,

T G-R
