Choosing A Webhost:
A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation. more...

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,
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
tar xvf foo.tar | /sbin/restorecon -f -
Would probably be better
