Could rhn_check for RHEL5 ever be updated so that the display/output is equivilant of rhn_check in RHEL4? Verbose doesn’t cut, as it gives too much inforamtion.
I use rhn_check (via Putty) because it refreshes the package list back at RHN, thus I know everything is installed. Yum works, however I have to have the system check RHN after Yum’s done to make sure there’s nothing left.
