Ok, my mistake... I attempted to RTFM before doing this, but it seems the
FM isn't quite up-to-date on this subject. ;)  I took a look at the
/usr/lib/dpkg/methods/apt/install script and it does correctly call
apg-get autoclean now (dangit... I distinctly remember looking at it last
year and it seeing apt-get clean in there.  ;/ )

Ah well, live 'n learn.


Thanks,
Mike
