No, the file permissions are set in the tar-file from the list generated from the special versions of chmod. A tar-file can be made as any user, you just need a tar which can understand how to put the right permissions in the tar file. -- Tom Lees <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> http://www.lpsg.demon.co.uk/ PGP Key: finger [EMAIL PROTECTED], http://www.lpsg.demon.co.uk/pgpkey.txt. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
