Hi Guix, The system test "basic" fails on commit 7d1f21c69aa89e4c7c57ace26af80d168157b243 (master). To reproduce, check out that commit and run: make check-system TESTS="basic" For the record, this is on an x86_64-linux GuixSD system using an ext4 root file system. Here's the error (I've sanitized the output, which apparently contained some unprintable characters, and removed some lines for brevity): --8<---------------cut here---------------start------------->8--- qemu-system-x86_64: warning: hub 0 is not connected to host network [?7l [0mSeaBIOS (version rel-1.11.2-0-gf9626ccb91-prebuilt.qemu-project.org) iPXE (http://ipxe.org) 00:03.0 C980 PCI2.10 PnP PMM+0FF91280+0FEF1280 C980 Press Ctrl-B to configure iPXE (PCI 00:03.0)...

I checked the Guix checkout and the retained directory of the failed derivation (i.e., the directory produced by guix build --keep-failed /gnu/store/...gjmid5-basic.drv), but I don't see it anywhere. 2) The test seems to have failed becuase of the following issue, which is mentioned in the output above: --8<---------------cut here---------------start------------->8--- 0 (mount "/dev/vda1" "/real-root" "ext4" 1 #) In procedure mount: No such file or directory --8<---------------cut here---------------end--------------->8--- The next steps are probably to look into whether /dev/vda1 or /real-root exist when that call is made, and if one of them is missing, investigate why it doesn't exist. -- Chris
