Description of problem:
When installing some packs like sun, acroread etc which are not signed one has
to disable gpgcheck in yum.conf, which sometimes leads to being left in that
order. This poses a risk.
In my view yum should have a command line switch to disable gpgcjeck for that
particular invocation so that yum.conf is not disturbed and also if gpgcjeck is
disabled then a warning message whould be displayed to the user.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
yum in fedora 7 has this feature.
