... and the problem is that half of the variables are not
automatically managed, and the other one not by plain debconf but by
dbconfig-common.
dbconfig-common's feature to generate include files would be nice to
use, but I have no idea how to include something in an ini-style file
...
(Actually, /etc/dbconfig-common/phpgacl.conf would already be usable.
Which is also not purged ...)
And it also doesn't help for the changed smarty_dir var ...
A workaround for this bug would be to change smarty_dir not in the
shipped conffile but to replace it in the postinst. While that would
make piuparts happy, the whole situation is quite messy ...
And I'm not sure it's enough because the replacing in the postinst
changes whitespace, although this could be fixed with a little perl:
