My original notes are poorly ordered. I should have noted that the media had also been booted prior to this "try mouting on an older system" activity. That activity includes a growfs. So the media was no longer exactly as it had been when the .img was generated. > The result was: >=20 > # mount -onoatime /dev/gpt/rootfs /mnt > UFS2 superblock failed: CGSIZE(fs) (32776) > fs->fs_bsize (32768) > mount: /dev/gpt/rootfs: Invalid fstype: Invalid argument >=20 > Note that the size difference is: 8. >=20 > I expect that an amd64 context produced the ufs file system that > is in the official snapshot's .img file.

(So: a week > older .img file.) Again: I'd also booted the media prior to this "try mouting on an older system" activity.
