A simpler file format might be better. All I can add is that having this in the front-end that takes its answers from a flat file is very good for doing things like installing security updated ssh on large clusters of servers you don't have primary control over or cannot guarantee any particular configuration (other than a patched debconf); scp answers target:/etc/debconf/answers ssh target "DEBIAN_FRONTEND=Managed apt-get install ssh" About 2 minutes work and 10 minutes to wait for about 40 hosts. The RedHat admin took all day and then some to do a similar number of red bin hakt hosts. If it was possible to supply the debconf.conf location via an environment variable, then you could override it for one installation with two config files. Or switch between two `stack' drivers. You could even add another database via an environment variable that is queried in preference of the defaults in the package template, but after any local config databases specified in /etc/debconf.conf. So then it could be something like ssh -R 389:ldap:389 root@target \ "DEBCONF_FALLBACK=LDAP:host=localhost apt-get install ssh" To log in, specify a temporary forwarded tunnelled ldap connection to debconf and then install ssh. or scp config.dat root@target:/var/run/config.dat ssh root@target "DEBCONF_FALLBACK=File:/var/run/config.dat apt-get install ssh" or, if you know that you can at least get one known entry added to /etc/debconf.conf, but not left as default: ssh root@target "DEBCONF_BACKEND=easydb apt-get install ssh" Take a look at the attached patch, works in the trivial testing I've attempted here and with the above examples. Don't know if you want to put those functions in a separate module or change their semantics a bit; that's a rough cut. -- Sam Vilain, firstname.lastname@example.org WWW: http://sam.vilain.net/ 7D74 2A09 B2D3 C30F F78E GPG: http://sam.vilain.net/sam.asc 278A A425 30A9 05B5 2F13 Real software engineers don't comment their code.
