Hi all, I just tried the previous command on Device C, an x86_64-linux Guix System:
~ $ guix time-machine --commit=deeb7d1f53d7ddfa977b3eadd760312bbd0a2509 -- build qtwebengine --derivations --system=aarch64-linux --no-grafts --dry-run <lots of non-error prints> /gnu/store/gnrk76mlrv3ipm2k3lpmy1533mn9dqc3-qtwebengine-6.5.2.drv As suspected, the hash matches that of device A. I'm tempted to reflash Device B, wipe and reencrypt the SD (which has /gnu/store), and reinstall Guix, but I also want to get to the bottom of this. So long as this thread doesn't get stale, I'm happy to try whatever suggestions people have. -Zacchae
