Description Dirk Wiesenthal

When uninstalling an App, the list of explicitely uninstalled packages is compiled from "DefaultPackages" and "AdditionalPackages$ROLE".

When the additional packages are essentially DefaultPackages of another App, this App is effectively uninstalled.

Happened in opsi (in fact, the only App using this feature). It uninstalls Samba 4 upon removal.

For the actual issue of opsi + samba4: It could be a workaround to set the samba4 app as RequiredAppsInDomain.

simple, do not (never) uninstall "AdditionalPackages$ROLE"

for the opsi + samba4 scenario, uninstalling samba4 more or less catastrophic

No, it doesn't need to be installed in the domain. It is still okay to install Samba 3 in the domain.
