Currently, Portage writes the effective emerge command to /var/log/emerge.log, showing what was requested, and then it writes each major step in the process. However, it does not write the list of packages to be merged, such as printed by `emerge -p`. This means that during a log install (e.g., KDE), I am not sure whether a particular other dependency is scheduled for merge (and what version/slot if it is). It would be convenient for Portage to also log the execution plan between the command and the actual execution.
