Would that be a feature for dpkg?I had a branch that extends «dpkg --audit» with checks for unknown database files under /var/lib/dpkg/, replicating in a built-in way what the dpkg postinst script is currently doing (for that one-time db recovery code). I guess that could be extended further to also check for stuff under /var/lib/dpkg/info/. What are the checks you had in mind? Whether there are files there for packages not currently preset? Perhaps also for files that should not be present for say a package in config-files state? Anything else?
I would like find all non package files on my filesystem. Currently I use this:
comm -13 \
<(dpkg-query -Wf '${db-fsys:Files}\n' | cut -c2- | \
sed -Ee 's#^/s?bin#/usr&#' -e 's#^/lib#/usr&#' | sort -u) \
<(find / -xdev \
\! -regex '/\(boot/grub\|etc/\(alternatives\|ssl\)\|home\|root\|tmp\|var/\(backups\|cache\|lib/dpkg\|log\|tmp\)\).*' \
\! -path '*/__pycache__*' | sort)
I.e.: compare the list of files produced by dpkg-query with the list
from find and exclude some directories that are allowed to change.
I would like to reduce exclude this list and /var/lib/dpkg, thus my
question for --control-path. What do you think of a dpkg tool producing
such a list, like dpkg --audit-unknown?
Cheers Jochen
