rpm scriptlet ordering for install/remove/upgrade using yum

问题

I'm working on a bug in our rpm scriptlets which is probably originating from order in which our scriptlets are executed during package install/removal/upgrade. We are using yum on Redhat Enterprise.

Obviously I first need a good understanding of the order of the rpm scriptlets - and interestingly enough I have not found a good summary of this anywhere.

From what I gather this is the scriptlet ordering for upgrades:

%pretrans of new package
%pre of new package prein
package install
%post of new package postin
%preun of old package
removal of old package
%postun of old package
%posttrans of new package

However it doesn't list the scriptlet orderings for installing a new package not previously on the system (i.e. not an upgrade) and for removing one? From the above ordering I am able to guess how these orderings might look, but I'd like to get some educated opinion on this as well...

Package order for installing a single package for the first time:

%pretrans of new package
%pre of new package
package install
%post of new package
%posttrans of new package

Package order for removing a single package:

%preun of old package
removal of old package
%postun of old package

If you are installing two different packages at once (e.g. primary, secondary ), where one depends on the other (secondary requires primary), the order is:

%pretrans of primary
%pretrans of secondary
%pre of primary
installation of primary
%post of primary
%pre of secondary
installation of secondary
%post of secondary
%posttrans of primary
%posttrans of secondary

When removing these packages at once, the order is:

%preun of secondary
removal of secondary
%postun of secondary
%preun of primary
removal of primary
$postun of primary

Your educated guess is correct - only the steps that are relevant.
