I did a sudo apt-get upgrade on a fresh Ubuntu 12.04.3 and there was a long list of updates and then this:
Setting up grub-common (1.99-21ubuntu3.14) … Installing new version of config file /etc/grub.d/00_header … Installing new version of config file /etc/grub.d/30_os-prober … Installing new version of config file /etc/grub.d/20_linux_xen … Installing new version of config file /etc/grub.d/10_linux … Setting up grub2-common (1.99-21ubuntu3.14) … Setting up grub-pc-bin (1.99-21ubuntu3.14) … Setting up grub-pc (1.99-21ubuntu3.14) … /usr/sbin/grub-setup: warn: Attempting to install GRUB to a partitionless disk or to a partition. This is a BAD idea…
However it completed without errors and I rebooted - the VPS seems to be running fine. Was that really a bad idea or not? What are best practices with regard to apt-get upgrade and dist-upgrade?
(I saw a similar question but it wasn’t related to real GRUB warnings)
