Sorry to be asking such a simple question. Is it possible to preserve file contexts using tar? I would have thought -p would do this, but it appears no, atleast on RHEL4 and FC4.
The reason to do this is a use tar to install modified config files on new machines. Having to relabel after doing this is somewhat slow. Perhaps there is a better solution?
Thanks, Scott Wilburn

Have you looked at star?

Usage is: # create an archive including xattrs star -xattr -H=exustar -c -f foo.tar <list of files to archive> # extract the archive, preserving any xattrs in it star -x -f foo.tar
rsync also has support for xattr preservation (-X, --xattrs), at least in FC4.
An option for GNU tar might be to selectively apply restorecon to the files you are extracting if they are being extracted to the same path on the destination machine as on the source machine and both machines have the same policy, e.g.: tar xvf foo.tar | xargs /sbin/restorecon

Would probably be better
