Perhaps release-notes should suggest to run dpkg --verify after a
dist-upgrade anyway - i assume it doesnt hurt to do so?
Happy to suggest and edit text for release notes: i would want to know:
- how do i know if the system is fine?
i was assuming that it would output nothing if everything is fine,
but that seems to be far from the case. I get huge amounts of output
that is very hard to interpret, i assume it's showing a 'c' for every
single changed conffile, and 'missing' where i deleted conffiles.
But why are some lines contain question marks? we would need a lot
of explanation here to make this useful for users (unfortunately, the
dpkg man page is very confusing about this option, and doesnt have
any of this, as far as i can understand)
- if something went wrong:
a) how do i know? would there be an obvious error message? do i need to check the exit status?
b) what would i do?: reinstall some packages? reinstall the whole system?
(maybe this should be in a bug against release-notes)
