No archive format changes are being proposed by this case. The archive format introduced by the extended attributes case (PSARC/1999/209) was integrated into the cpio and tar sources over six years ago (07/29/2001). The new headers introduced at that time are also used for the extended system attributes for which this case adds support. > >Keep in mind that it is not acceptable to have archive enhancements that are >not >compatible with already existing archive format enhancements from other >programs. See: > >http://cdrecord.berlios.de/old/private/man/star/star.4.html There is no incompatibility here. The web page above includes: #define LF_EXTATTR 'E' /* Solaris Extended Attribute File */ which is the archive format used by this case. If you are concerned that external to Sun applications don't have access to the functions defined by PSARC/2007/315 (which defines them to be consolidation private and are used to process extended system attributes), I would suggest that you try to convince the submitter of that case to make them public. Those interfaces are not controlled by the project team that submitted this case. - Don > >SCHILY.fflags > >for more information. > >J?rg
