Supposing the composite grub.conf looks like this:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda5
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Fedora Core (2.6.9-1.3_FC2)
root (hd0,0)
kernel /vmlinuz-2.6.9-1.3_FC2 ro root=LABEL=/
initrd /initrd-2.6.9-1.3_FC2.img
title Fedora Core (2.6.8-1.521)
root (hd0,0)
kernel /vmlinuz-2.6.8-1.521 ro root=LABEL=/
initrd /initrd-2.6.8-1.521.img
title Red Hat Linux (2.4.20-8)
root (hd0,0)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/1
initrd /initrd-2.4.20-8.img
So, when a new kernel is to be added, how does grubby know whether to add an
entry with "root=LABEL=/" or "root=LABEL=/1"?
