[wpkg-users] Software always installs before remove

[Rainer Meier]

Hi Heiko,

What you're seeing is the "upgrade-before-remove" feature. It makes sure a 
package is updated to the latest version before uninstall takes place. Thus 
giving system administrators the possibility to fix package issues (e.g. invalid 
remove commands).

You can disable it by configuration or command line switch but I recommend not 
to do so. Disabling this feature might leave you in a very difficult situation 
if you have to fix a package issue before removing a package (e.g. your packages 
completely miss any remove instructions).

Search the list for some discussions on this feature.

In the logs you will see that WPKG internally performs an "installation". The 
installation task checks your current system state and makes sure the package 
installed is correctly installed and up-to-date.
In most cases the installation will just run the checks and detect that the 
package you just removed is installed properly and already up-to-date. So it 
will not perform any action. After this WPKG is going to execute the remove 
commands just as intended; but this way WPKG assures that your remove commands 
are applied on a defined state (application properly installed and updated).

This way you just need to assure that the latest revision of the package 
uninstalls properly and WPKG makes sure that this revision is installed and then 
removes correctly.

br,
Rainer
