About /var/cache/apt/archives/, I now use a symbolic link (this was suggested somewhere in the forum): Code: # ln -s /media/mmc3/var/cache/apt/archives /var/cache/apt/ (mmc3 corresponds to my ext2 partition here, but I suppose that it can be something else).
# ln -s /media/mmc3/var/cache/apt/archives /var/cache/apt/
