Hi! The “dtmp/” issue is not new. It appeared already in these bugs:
https://issues.guix.gnu.org/27032 https://issues.guix.gnu.org/27034 https://issues.guix.gnu.org/29676 In all cases it happens in tests/store.scm: test-name: verify-store + check-contents This bug happened on x86_64 and aarch64. The issues 27032 and 27034 where reported when the installer used a unionfs. Probably it was hidden when switching to an overlayfs. This issue 41654 and 29676 show the “dtmp/” error when running this test on an NFS share. Bye Stefan
