Jakub,

Do you have an example of a package that does 'the right thing'? What should
the package do? The manpage of pam-auth-update says that pam-auth-update
--remove should be called before removing the module, but this isn't correct
if the module remains for another architecture.

Should pam-auth-update be made multiarch-aware and handle this automatically?

If binaries from multiple architectures call pam on the same system, and a
pam-module is installed for one of these architectures, but not for the other
one, the pam configuration cannot be correct for both of them.

Are these issues documented somewhere?

Cheers,

Ivo
