What does "rather unhappy" mean?  The upgrade process remembers what
device you installed grub to before and uses the same location when grub
needs to be reinstalled.  Also, installing grub to /dev/sda1 only
modifies sector zero, which LVM does not use, so while it may not boot,
it wouldn't cause any harm.
