[gentoo-user] Spurious warnings?

Here's an example of a (possibly) useless log warning. I say useless because I don't know (how would I?) whether this was updated from version 0.30 or not.

I get these kinds of messages regularly. Sometimes, I say, "right. I did that last week, why is it telling me again?".

How do others know if a warning applies after any system/world update?

LOG: postinst

The database format has changed between 0.30 and 0.40.
You may need to update all your local databases and caches.
To do so, please run the following commands:
(for each user) $ update-mime-database ~/.local/share/mime/
(as root) # update-mime-database /usr/local/share/mime/

portage doesn't have a mechanism to tell you to do something and then record
that you did in fact do it. So it always tells you to do something.

We often attempt to ascribe human intelligence to software.
It's a side-effect of being human. Be alert for it :-)

genlop -u pkgname will show you the version that was unmerged and the new
version. It's up to you to decide which side of 0.30 and 0.40 they lie.
