Well, dpkg certainly handles conffiles moving from one package to the
other if you use the proper "Replaces" field like for any other file.
Michael, what does your system say for "dpkg -S
/etc/console-setup/remap.inc" ?
I think it will give the new package. And the file will only appear in
dpkg -L of the new package too. However it's true that the "Conffiles"
field is not always properly updated. The conffile often ends up being
listed on both packages.
I instrumented the "t-conffile-replaces" test case like this:
--- a/t-conffile-replaces/Makefile
+++ b/t-conffile-replaces/Makefile
@@ -9,6 +9,9 @@ define VERIFY
test "`$(PKG_STATUS) pkg-conff-original`" = "install ok installed"
test "`$(PKG_STATUS) pkg-conff-takeover`" = "install ok installed"
test "`$(DPKG_QUERY) -S /test-conffile`" = "pkg-conff-takeover: /test-conffile"
+$(DPKG_QUERY) -W -f'$${Conffiles}\n' pkg-conff-original
+echo "Takeover:"
+$(DPKG_QUERY) -W -f'$${Conffiles}\n' pkg-conff-takeover
cmp ref-conffile /test-conffile
endef
It gives various results depending on how dpkg is called:
test-two-run-ordered & test-two-run-reverse:
/test-conffile e8a2f071ccdf836fc77865fba3ee8558
Takeover:
/test-conffile 45a18cfae67be6e80a5ec2ee60579bf3
test-one-run-ordered:
/test-conffile 45a18cfae67be6e80a5ec2ee60579bf3
Takeover:
/test-conffile newconffile
test-one-run-reverse:
/test-conffile newconffile
Takeover:
/test-conffile 45a18cfae67be6e80a5ec2ee60579bf3
There's room for improvements here.
Cheers,
