maintainer script factorization

["Martin Fuzzey" <mfuzzey@gmail.com>]

Hi all,

frequently maintainer scripts modify the same files and to avoid duplication of path names etc in all scripts I was wondering if they could be factorized anywhere.
The obvious solution of installing something like /usr/share/package/common.sh and sourcing it in the maintainer scripts doesn't work as the package files may already have been removed.

Any ideas or is this impossible?

Thanks,
