why? Maybe I am naive, but assume you have 3 packages X, Y
and Z, where Z depends on X and Y. make update for Z could
then: build, deinstall & reinstall package X, build
deinstall & reinstall Y and then build deinstall &
reinstall Z. Where is the problem with this? IMO this would
avoid most problems with make update. Say, if build Y
fails, then we would have a new version of X installed and
old versions of both Y and Z installed. Maybe this leads to
some slight inconsitencies, but still better then having
everything deinstalled. I know, this is not a problem with
3 packages, but think of a whole tree of packages.
