I've often wondered about that when >coding in C. Adding chase? with any default to set-file-owner, set-file-group, and set-file-timespecs isn't particularly important, or at least I can't recall ever desiring to do any of those operations to a symlink. Which would make it less confusing to add chase? with a default of #f only to file-info, and thus default to calling lstat as I too have done as you have. - Harold
