Hey, With recent Guix revisions ( for example) I've had some apparentlyrandom segmentation faults with grafts. I've encountered this on twomachines, both times it appears not to happen repeatably, as re-runningthe graft can work. I encountered this when running guix package -u, andrunning it again eventually worked. One of the logs mentioned not being able to allocate memory. The machinethis was running on has 16GB of RAM, plus 16GB of swap, and most of thememory was free, so I think using all of this is unlikely.
