+### coreutils: FAIL: tests/tail-2/inotify-dir-recreate
+
+The inotify-dir-create test fails on "remote" filesystems such as overlayfs
+(Docker's default filesystem) due to the filesystem being mistakenly recognized
+as non-remote.
+
+A relatively easy workaround to this is to make sure that a somewhat traditional
+filesystem is mounted at `/tmp` (where `guix-daemon` performs its builds). For
+Docker users, this might mean [using a volume][docker/volumes], [binding
+mounting][docker/bind-mnt] from host, or (for those with enough RAM and swap)
+[mounting a tmpfs][docker/tmpfs] using the `--tmpfs` flag.
