This if (and the following one) seem redundant because the previous line (260) already checked this condition. I think this could error immediately with "no shapshotter and rootfs set for container".
Or is 260 supposed to be || ? With && it means that if one of them is the empty string the "else" block below could fail in an unexpected way.

These errors are only returned when all 3 are empty. And there are separate error messages for each missing field. I think i retained that same logic with the change.

The second missing field block (line 265) would never be hit, it's dead code, and there are unhandled error cases:
c.Snapshotter |
c.SnapshotKey |
s.Root.Path |
result |
|---|---|---|---|
| "" | "" | "" | errors.Errorf("no snapshotter set for container") |
| "overlay" | "" | n/a | (goes to line 282 and may error because snapshotkey is "") |
| "" | "foo" | n/a | (goes to line 282 and may error because Snapshotter is "") |
| "overlay" | "foo" | n/a | (goes to line 282 and shouldn't error) |
| "" | "" | /something |
(goes to line 269 and shouldn't error) |
right?

I think you are reading it wrong on your second line in the table. It won't go to 282, it goes to 265 and errors.

nit: is this required? filepath.IsAbs("") seems to return false on linux, but maybe it's not guaranteed to be on all platforms?
