Hi Heiko,

...sorry my question was unclear.

Suppose one would do an emerge @world...and then BOOOM! a powerfailyre
would stop the whole thing. Further suppose the filesystem, the
hardware and anything has survived luckily -- only emerge @world needs
to be restarted.
And one does NOT an emerge --resume but an emerge @world.
In this particular case...how does emerge knows from the previous
emerge @world what packages has been recompiled already and are "PIE"?

How can I check, whether a binary is "PIE"-conform ("pie-conform" is
a freaky funny language hack :) ;) )  ?

Cheers
