Answer 1

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

Answer 2

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
