I uploaded a new package version in which the not upstreamed patches are dropped, the maintainer is set to myself and the vcs fields are updated accordingly. With #874387 Felix is searching for a new maintainer for this package; what are the requirements for me to become such?
Also, I like to ask a technical question: What is the common dealing with state file upon package purge? Vnstat saves the network statistics under /var/lib/vnstat and as this folder is listed in debian/vnstat.install, dpkg warns upon purge operation that this directory cannot be deleted, because it is not empty. Should the directory be emptied in the postrm script or is this warning acceptable?
