Calling db.Checkpoint with destDir like ./foo returns no such file or directory #4268
Description
IIUC, this is because mkdirAllAndSyncParents is called, append an empty string as parent path in parentPaths, and fs.OpenDir on an empty string fails with the error no such file or directory.
Using pebble v.1.1.3
