help:aix环境下的tar文件与redhat as4环境下的tar文件？

netbeta

在aix5.1下执行
＃tar -cvf /softlib/backup.tar      /PROJECTREP/AMIS2

ftp到redhat as4下，执行
#tar -xvf backup.tar

出现以下提示：
“tar: Removing leading `/' from member names
/PROJECTREP/AMIS2/CVSROOT/
/PROJECTREP/AMIS2/CVSROOT/Emptydir/
/PROJECTREP/AMIS2/CVSROOT/loginfo

在32位和x86－64环境都是同样的错误！

但恢复一个以前的tar文件居然正常，巨奇怪！

可能 tar 版本不同吧?
