deb-conffiles(5)          (2021-04-13)           deb-conffiles(5)

     NAME
          deb-conffiles - package conffiles

     SYNOPSIS
          DEBIAN/conffiles

     DESCRIPTION
          A package declares its list of conffiles by including a
          conffiles file in its control archive (i.e. DEBIAN/conffiles
          during package creation).

          This file contains a list of files, one per line, with an
          optional leading flag separated by whitespace.  The
          conffiles must be listed as absolute pathnames.  Trailing
          whitespace will be trimmed, but empty or whitespace-only
          lines are not accepted.

          Files without a flag should exist in the binary package,
          otherwise dpkg(1) will ignore them.

          There is currently only one flag supported, remove-on-
          upgrade, to mark that a conffile needs to be removed on the
          next upgrade (since dpkg 1.20.6).  These files must not
          exist in the binary package, as both dpkg(1) and dpkg-deb(1)
          will not accept building nor processing such binary
          packages.

     EXAMPLE
           /etc/alternatives/README
           /etc/cron.daily/dpkg
           /etc/dpkg/dpkg.cfg
           /etc/logrotate.d/dpkg
           remove-on-upgrade /etc/some-old-file.conf

     SEE ALSO
          dpkg-deb(1), dpkg(1).
