deb-prerm - package pre-removal maintainer script
A package can perform several pre-removal actions via maintainer scripts, by including an executable prerm file in its control archive (i.e. DEBIAN/prerm during package creation). The script can be called in the following ways: prerm remove Before the package is removed. old-prerm upgrade new-version Before an upgrade. new-prerm failed-upgrade old-version new-version If the above upgrade fails. prerm deconfigure in-favour new-package new-version [ removing old-package old-version ] Before package is deconfigured while dependency is replaced due to conflict. prerm remove in-favour new-package new-version Before the package is replaced due to conflict.
