[15:25] <kelleyk1> Howdy, everybody — I'm having an issue with unattended (preseeded) installs of vivid and was hoping someone had words of wisdom to share.
[15:26] <kelleyk1> Namely, starting with 15.04, even in a network-booted VM with only a single drive, the grub-installer phase prompts to confirm which device GRUB should be installed to.
[15:27] <kelleyk1> There's an upstream (debian) issue that was resolved by adding support for preseeding with the string "default", but it doesn't seem like that patch is in the version that vivid is using.
[15:27] <kelleyk1> Does anyone have any ideas?  It'd be very nice to be able to just take the default selection, since the installer *is* coming up with the proper value on its own.
