Non-obsolete conffile /etc/network/if-up.d/samba missing due to wrong rm_conffile calls in samba package

[Tristan Schmelcher]

On my system, the conffile /etc/network/if-up.d/samba is missing. This is because the samba package's maintainer scripts run rm_conffile for it:

$ grep -F 'dpkg-maintscript-helper rm_conffile' /var/lib/dpkg/info/samba.*
/var/lib/dpkg/info/samba.postinst:dpkg-maintscript-helper rm_conffile /etc/network/if-up.d/samba 2:3.6.5-6~ samba -- "$@"
/var/lib/dpkg/info/samba.postrm:dpkg-maintscript-helper rm_conffile /etc/network/if-up.d/samba 2:3.6.5-6~ samba -- "$@"
/var/lib/dpkg/info/samba.preinst:dpkg-maintscript-helper rm_conffile /etc/network/if-up.d/samba 2:3.6.5-6~ samba -- "$@"
/var/lib/dpkg/info/samba.prerm:dpkg-maintscript-helper rm_conffile /etc/network/if-up.d/samba 2:3.6.5-6~ samba -- "$@"

But this conffile is not obsolete:

$ grep -F /etc/network/if-up.d/samba /var/lib/dpkg/status
 /etc/network/if-up.d/samba 2c617f0d1baebc4ba4177087a7eefc57

Indeed, looking inside the deb file, /etc/network/if-up.d/samba is still there.

Actual behaviour:

samba runs rm_conffile for non-obsolete conffile /etc/network/if-up.d/samba, so it is deleted on upgrade if the previously-installed version precedes 2:3.6.5-6.

Expected behaviour:

Maintainer scripts should not delete non-obsolete conffiles.
