# In standard redhat like linux os with grub2 above version of 7, the boot configuration in "grub.cfg" is like:
#
# insmod part_msdos
# insmod xfs
# set root='hd0,msdos1'
# if [ x$feature_platform_search_hint = xy ]; then
# search --no-floppy --fs-uuid --set=root --hint='hd0,msdos1' d34311d7-62fd-419e-8f19-71494c773ddd
# else
# search --no-floppy --fs-uuid --set=root d34311d7-62fd-419e-8f19-71494c773ddd
# fi
#
# But in Rocky Linux 9.1 of official templates in Oracle Cloud, only the following method will effective:
# The expect component in grub file should be like "search --no-floppy --fs-uuid --set=root 9340b3c7-e898-44ae-bd1e-4c58dec2b16d".

# An array for row number of "search --no-floppy --fs-uuid --set=root..." minus row number of "insmod part_".
IpaSpace=()
# Static how many times does "insmod part_" appeared and storage rows in array of "InsmodPartArray",
# storage minus rows in arrary of "IpaSpace"

# A typical buddle sort for compare whether the current variable "minArray" is greater than the order of number in "IpaSpace" of current cycle.
# One number of row minus another one shouldn't be less than "0".
# If "minArray" is greater than the order "j" in array of "IpaSpace", the less one "j" will replace the former "IpaSpace".

# insmod xfs
# search --no-floppy --fs-uuid --set=root 9340b3c7-e898-44ae-bd1e-4c58dec2b16d
