Description of problem:
The postinstall script does the following:

if grep "Red Hat" /etc/redhat-release; then ....

which results in the matching string being echoed to the terminal. I
dont think it is desireable for output to appear in the middle of
up2date or a rpm transaction :) Trivial fix would probably be to
redirect stdout and stderr output to /dev/null or something like this:

if grep "Red Hat" /etc/redhat-release > /dev/null 2>&1; then ...


Version-Release number of selected component (if applicable):
redhat-artwork-0.95-1


Thanks.
