Eelco Dolstra deb4f88c2c * Let the GRUB menu builder detect whether /boot is on a different
partition from /.  If so, copy the kernels and initrds to /boot and
  use paths relative to /boot in the GRUB configuration file.  This
  makes the boot.loader.grub.bootDevice option obsolete.  (Is there a
  way to mark obsolete options?)  It also makes it unnecessary to set
  boot.loader.grub.copyKernels, although that option is still
  available since it can speed up GRUB if the Nix store is very
  large.

# This configuration has / on a LVM volume. Since Grub
# doesn't know about LVM, a separate /boot is therefore
# needed.
#
# In this example, labels are used for file systems and
# swap devices: "boot" might be /dev/sda1, "root" might be
# /dev/my-volume-group/root, and "swap" might be /dev/sda2.
# In particular there is no specific reference to the fact
# that / is on LVM; that's figured out automatically.
