It isn't clear if the following is a bug, but it's a real question. Besides, this was the only cpio-related mailing list that I could find.
I'm writing an emacs application to handle cpio(1) archives. It is intended, in part, to work like tar-mode and dired. However, with some archives (and some entries within those archives, it looks to me like the filesize
field is too large by one byte. The archives still unpack properly, but manual checking of the filesize
field reflects that bug for those entries.
I think I've reflected the GNU cpio(1) code correctly. I'd like to know if I've stumbled across something known (and therefore also what that is) or if it's a new bug.
