I need to backup some conf files of my package during upgrade into directory
called e.g `/mypackage-<old-version>`.
So I'm trying to get old package version in `%pre` scriplet and doing it in the
following way:
```
%pre
VERS=$(rpm --queryformat='%{VERSION}' -q mypackage)
VERS_ALTERNATIVE=$(rpm -qi mypackage | awk -F': ' '/Version/ {print $2}')
```
And the strange thing is that `VERS` variable got version of the package that
I'm upgrading to (newer), while value of `VERS_ALTERNATIVE` contains version of
the package that I'm upgrading from (older).
I'm do realize that invoking `rpm -q` in RPM scirplets is not the best idea,
but anyway for me seems like this behavior is some kind of bug, as I suppose
that in all cases result of `rpm -qi` and `rpm --queryformat` should output
similar information.
I got this in CentOS 8 with RPM version 4.14.2. Same problem in CentOS 7.
