Package: grub2 Severity: wishlist Hi,
I'm currently working on a script for a customer to generate a customized image for them to use on their embedded devices. The output of this script will be a CompactFlash device, ready to be put in their device (an Atom-based board). This script must run fully noninteractive, so has DEBCONF_FRONTEND=noninteractive. One of the things the script must do is install a boot loader, in casu grub2. However, this fails because grub2 assumes that it must at all times be installed to a boot record if it's installed somewhere, and will fail to install properly if that isn't true. Now while it can be useful to have a bootloader be automatically configured upon installation, it's fairly annoying if I have to resort to ugly tricks to make the postinst script believe it doesn't have to do anything. Instead, I'd prefer it if it were possible to just tell it to not do anything, so that I can do this myself. A proposed patch (not tested, but gets the idea across): diff -ruN grub2-1.99.orig/debian/postinst.in grub2-1.99/debian/postinst.in --- grub2-1.99.orig/debian/postinst.in 2012-04-05 11:33:26.638928567 +0200 +++ grub2-1.99/debian/postinst.in 2012-04-05 11:45:43.746939629 +0200 @@ -291,6 +291,11 @@ configure) . /usr/share/debconf/confmodule + db_get grub2/configure_grub || true + if [ "$RET" = "false" ]; then + exit 0 + fi + if dpkg --compare-versions "$2" lt-nl 1.99-1; then # Force dpkg to replace this directory with a symlink. if [ ! -L /usr/share/doc/@PACKAGE@ ] && [ -d /usr/share/doc/@PACKAGE@ ]; then diff -ruN grub2-1.99.orig/debian/templates.in grub2-1.99/debian/templates.in --- grub2-1.99.orig/debian/templates.in 2012-04-05 11:47:12.058940963 +0200 +++ grub2-1.99/debian/templates.in 2012-04-05 11:46:53.330940571 +0200 @@ -43,3 +43,11 @@ .

Since we only db_get the value and don't db_input it, it's never shown to a user, and the default value shouldn't result in any changes. As such, this should be non-intrusive for the common case, while allowing people to bypass the autoconfiguration entirely if they don't need it, as in my case.
