Unfortnuatly i didn't find the specifications about the format of a CPIO archive, for example whats the "TRAILER!!!" and such. Can anybody help me out with the link or a hint where I can find the document?

There are many CPIO variants, most are undocumented. POSIX standardized an "octet-oriented" format (today called "odc") that is now documented as being one of the formats supported by pax: http://www.opengroup.org/onlinepubs/009695399/utilities/pax.html In the process of working on libarchive, I scraped together documentation for a number of cpio formats; you can see the result at: http://people.freebsd.org/~kientzle/libarchive/man/cpio.5.txt or get the mdoc source file at http://libarchive.googlecode.com/svn/trunk/libarchive/cpio.5 Cheers, Tim _______________________________________________ Bug-cpio mailing list Bug-cpio@... http://lists.gnu.org/mailman/listinfo/bug-cpio
