We've lost the thread here. Tar is not a tool to duplicate a file system. Never has been. Unless you can be totally sure that there are no special files or bits set for the files. This works with source trees that can use 'make'�to fill in the missing parts, and so is a popular archiver for source code distributions. cpio is designed to duplicate directory structures properly, including all unexpected things it may find in them. tar never was. Name length aside. If you use tar, you risk incorrect duplication of some files. Not so with cpio. That was all I was trying to point out.

Over which they control the contents and are sure there are no special files or odd bit settings. Otherwise they are playing dangerously. -- +============================+===============================+ | Roger Oberholtzer | E-mail: [EMAIL PROTECTED] | | OPQ Systems AB | WWW: http://www.opq.se/ | | Erik Dahlbergsgatan 41-43 | Phone: Int + 46 8 314223 | | 115 32 Stockholm | Mobile: Int + 46 733 621657 | | Sweden | Fax: Int + 46 8 302602 | +============================+===============================+ _______________________________________________ Linux-users mailing list [EMAIL PROTECTED] Unsubscribe/Suspend/Etc -> http://www.linux-sxs.org/mailman/listinfo/linux-users
