su
cd /
tar cvf xxx.tar etc/cups/printers.conf
cd
tar xvf /xxx.tar
ls -al etc

and look at the ownership of the cups directory and compare it to the
ownership in /etc.

This is a changed behavior in tar(1), (at least from Ubuntu 10.04 LTS,
which I just verified.)

Note that it only happens when when tar'ing file names in a directory,
and not the directory itself, (tar cvf xxx.tar etc/cups, and restoring,
everything has the correct ownership/permissions.)

See, also:

    http://www.gnu.org/software/tar/manual/html_node/Directory-Modification-Times-and-Permissions.html

for some details, where it would seem that the behavior is
acceptable-at issue is that it changed between the last versions of
Linux, and the newer.

    Thanks, Don,
