I've got a fresh install of RHEL4 on a 1st gen Compaq DL320 (P-III 800, 1GB, SCSI).
I just ran up2date for the first time (from cli)
It did all the required checks, pulled all the files.... and then sat for about 7 minutes seemingly doing nothing (nothing in messages, the up2date log, no disk activity, etc) after downloading the final rpm (which happened to be xpdf)
Then it finally went to "Preparing... blah blah blah" and did the install.
