Good point! However in most cases people use jffs2 or something similar. So
there are chances that the files are still in the filesystem buffer/cache when
they are deleted. However we cannot exclude that writes do occur, but
unfortunately we will have to do a serious rewrite of dpkg to prohibit it of
writing out files.

Well it is a valid point, but just as in the case of the localepurge package
we cannot really take responsability for that. I also believe that the chances
of having a package breaking in such a way are very small. Eventually we can
put some logic in the removal scripts that it leaves files with a higher link
count in place.



PS to Bruno : The new modular X already makes it possible to install less
unneeded X stuff
