Currently the lib that is being preserved is shown at the bottom of a normal merge... the problem is that when that merge fails, nothing is shown and, if I try to know what lib was preserved, emerge -pv @preserved-rebuild won't tell me that either: # emerge -pv @preserved-rebuild These are the packages that would be merged, in order: Calculating dependencies... done!
