Hello,


That is impossible with pacman.

What you can do is create a local repository that is included in the 
automatic pacman upgrade. Then write a shell script that checks for 
updates of the arch package, merges it with your local changes, build it 
and add it to the repository. You should change the package name with 
e.g. a prefix or suffix and add the original package as a conflict to 
make it work properly. Now your custom version is available for the next 
pacman upgrade.
