Yes, and this doesn't happen in RHEL3, tar 1.13.25-13.
This behaviour change, different from RHEL3, is causing me a tremendous amount of grief. Why? I have an a tar archive whose first entry is "the current directory" with no-write permissions. tar fails because my current directories write permissions have been turned off. Great!
Fedora Core 3 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC5 updates or in the FC6 test release, reopen and change the version to match. Thank you!
I have found same upstream bug report: http://lists.gnu.org/archive/html/bug-tar/2006-04/msg00004.html using patch from upstream http://cvs.savannah.gnu.org/viewcvs/tar/tar/src/extract.c?r1=1.89&r2=1.90&diff_format=u fixed in tar-1.15.90-4
