pkg/lookup: Return ID-only pointers on ErrNo*Entries
Callers that only care about the IDs should try to convert the identifier to an integer before calling the Get* functions, so they can save the cost of hitting the filesystem and maybe or maybe not finding the other fields (User.Name, etc.). But callers that *want* the other fields but only actually need the ID can, with this commit, just call the Get* function and ignore ErrNo*Entries responses: user, err := lookup.GetUser(mount, userIDorName) if err != nil && err != ErrNoPasswdEntries { return err } Previously, they'd have to perform their own integer-conversion attempt in Get* error handling, with logic like: user, err := lookup.GetUser(mount, userIDorName) if err == ErrNoPasswdEntries { uuid, err := strconv.ParseUint(userIDorName, 10, 32) if err == nil { user.Uid = int(uuid) } } else if err != nil { return err } Signed-off-by: W.
