I don't understand this "insertion" business, thus neither "preserved". My
grub.cfgs contain zilch that is contained in custom.cfgs.
grub.cfg always contains:
…
### END /etc/grub.d/06_custom ###
### BEGIN /etc/grub.d/07_custom ###
if [ -f ${config_directory}/custom.cfg ]; then
source ${config_directory}/custom.cfg
elif [ -z "${config_directory}" -a -f $prefix/custom.cfg ]; then
source $prefix/custom.cfg;
fi
### END /etc/grub.d/07_custom ###
### BEGIN /etc/grub.d/10_linux ###
…
This code means custom.cfg is read at boot, with result that custom.cfg stanzas
are displayed before those contained within grub.cfg itself.

07… stanzas are displayed prior to grub.cfg's own (10…) stanzas. 41… entries are
displayed after. These numbers beginning filenames in /etc/grub.d/ are about the
order of presentation when grub is putting up a menu at boot.
