Not sure if this counts as a bug or a feature, but while trying to work on a problem I found that if you add an echo "" > /path/to/CONTENTS in pkg_postinst, from then on even if you attempt to unmerge the package, the files remain in place (which is pretty obvious, I know, since the CONTENTS file is used to back out an installation). Just passing on, Mike Reproducible: Always Steps to Reproduce: 1. 2. 3.
uhh you're right ... not quite sure to say about this :) if you `rm -rf /` then it is possible to make your system unbootable ...
in other words, yes, if you delete the db outlining what an installed package contains, then you cant remove it later ...
