When installing skipjack from cdrom on a Dell Inspiron 4000, install times are initially (after the first minute) estimated at 9 minutes. Throughout the entire install process, the estimated total time keeps increaing until it finishes (at 31 minutes). In previous RHL releases, the total time was fairly accurate (ie +/- 20%) after the installer completed the first few packages.
Nothing has changed about the estimation process. There are some packages in the mix (like dev) which take a disproportionate amount of time to install compared to others, and I think this affects the estimation. The problem with dev taking so long has been corrected.
