That will probably be a problem if the DB is read-only, yes.
joeyh, any thoughts on this one?

I don't care where the frontend is running, but I know that the system
where the config script is running is the system which is being
configured. This might not be the place where the backend DB is
running, though.
So we might have a problem with code which looks like:
#! /bin/sh -e
. /usr/share/debconf/confmodule
if [ -e /etc/suck/get-news.conf ]; then
remoteserver=`grep remoteserver /etc/suck/get-news.conf | cut -d: -f 2-`
fi
if [ "$remoteserver" ]; then
db_set suck/get-news/remoteserver $remoteserver
fi
db_input medium suck/get-news/remoteserver || true
db_go || true
and then postinst:
#! /bin/sh -e
. /usr/share/debconf/confmodule
if [ ! -f /etc/suck/get-news.conf ]; then
cp /usr/share/doc/suck/examples/get-news.conf /etc/suck/get-news.conf
fi
db_get suck/get-news/remoteserver
sed -e "s/remoteserver:.*$/remoteserver: $RET/" /etc/suck/get-news.conf >
/etc/suck/get-news.conf.tmp$$
mv /etc/suck/get-news.conf.tmp$$ /etc/suck/get-news.conf
(Yes, I know about not copying from /usr/share/doc, but haven't fixed
it yet.)
This _will_ overwrite the local values, unless Debconf has a writable,
local DB as well. I really don't see how to implement this without a
writable DB. Is having a writable DB somewhere a requirement of
Debconf or is my code broken? If it's broken, what is the fix?
