When doing an upgrade from 10.0->beta8 using a DVD or 10.1beta8->beta9 from CDs there are packages installed even after the text says that installation was "Done". I have more information in case of beta9 with CDs:
- for CDs 1-4 the process was: the field for "bytes" became "Done", but it shown that there are some more packages (~60 for CD1, less for the rest). After those were installed, the number became "Done", but other packages were still installing
- for CD5 I realized that the number of packages shown in Total is not the same as the number needed to be installed from CD5, and here Total showed "Done/Done" while packages were still installed, but installation finished once the count for CD5 packages reached 0. :-)
