apt itself doesn't care since it doesn't touch the filesystem except for /var/cache/apt and /var/state/apt. the problem comes when apt asks dpkg to install a package, if the package has any file in /usr (which it always will even if its only /usr/share/doc/package/*) then dpkg will fail and the package will be broken. newwer versions of dpkg (may only be in CVS) i have heard have an option to not install files in certain places, say /usr or /usr/share. to allow for this very situtation. for now pretty much your only option is this kludge: drop to single user mode umount /usr apt-get rm -rf /usr/* mount /usr -- Ethan Benson http://www.alaska.net/~erbenson/
