I have file with content - part of ISO grub configuration - the interesting part is the last 8 lines ( the whole file is provided - in case the context matters )

msg "Modifying live '$1' bootloader menu '$2'"

info "Change menu name to ${2}"

msg "Modified '$1' with '$2'"
The purpose is to modify my ISO removing one menu and altering another.
I have this script - which takes two arguments - the iso profile to modify and the string to be used when modifying the menu.
The sed -i argument is removed for debugging purpose.
The first part work as intended - removing the menu providing proprietary drivers
# remove entry for proprietary gpu drivers
sed '/menuentry \"Boot with proprietary drivers\"/,+3d' "${kernels_cfg}"
I use double quotes because I want the second argument to be expanded - and it does expand - but sed does not edit the file and I cannot figure out why
# change entry for opensource gpu driver
echo sed "s/Boot with open source drivers/${2}/g" "${kernels_cfg}"
sed "s/Boot with open source drivers/${2}/g" "${kernels_cfg}"
if I run grep on the file - I get the line
$ grep -e 'Boot with open source drivers' <buildroot>/buildiso/<profile>/iso/boot/grub/kernels.cfg
