Hi!

Today I thought that it should be possible to work around this bug on my aarch64 system by mounting /tmp as a tmpfs, backed by swap on a small SD card, to prevent any issues due to my NFS root. This worked for the trap-cleanup-issue. But to my surprise this didn’t work out for the “dtmp/” error.

I was wondering, if using /tmp as a tmpfs on my virtual x86_64 system would make the test fail there as well. So I did 

sudo mount -t tmpfs -o size=768M tmpfs /tmp
guix build --check --no-grafts guix <at> 1.2.0-8.7624ebb

But there it was passing.

This is the interesting part from the log of the aarch64 system:
