RE: Help: Microsoft patent covers package download and upgrade
that's not the sequence that dselect and co. use though, as with debian, the
client computer determines which packages are needed by getting the lists
first. This patent doesn't have any bearing on Debian since the sequence
and methodology is different. Although the title of the patent may seem
suspicious, the crux of the matter is that it's quite a bit different of a
method than we use, so all is well ;-)
