[SOLVED] rpm scriptlet ordering for install/remove/upgrade using yum

Issue

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...


Solution

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
