Package: grub-pc Version: 1.95+20070507-1 I just installed grub-pc in a chroot, just because I wanted to try out grub-probe. I was somewhat horrified that it proceded to automatically install and configure itself. Only after checking the postinst did I see that it had not actually written anything to the MBR (which makes it a bit less of a problem), but that is absolutely not clear to the user!
I also wonder how this works when the package is installed from debian-installer which AFAIK takes care of setting up grub itself. I would strongly suggest to either not set up grub automatically or at least ask a debconf question whether the user really wants to set up grub. However, this should be done in such a way that the question does not get asked when grub-pc is installed by debian-installer. Note that the current grub does not even have a postinst! Also note the three errors while grub-probe is executed. These should be either avoided or suppressed. $ sudo aptitude install grub-pc [...] The following NEW packages will be installed: grub-pc 0 packages upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
