Hello,

I had two single quotes closing a variable in /etc/default/grub like this (due
to copy paste mistake from me):

# head /etc/default/grub
#GRUB_DEFAULT=0
GRUB_DEFAULT='Arch Linux, with Linux linux''
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"

When running grub-mkconfig with that configuration, this is the output:

# sudo grub-mkconfig -o /boot/grub/grub.cfg
Generating grub configuration file ...

done


As you can see there is no error, but the resulting file has a missing double
quote (at set default="Arch Linux, with Linux linux):

# sudo head /boot/grub/grub.cfg -n 25
#
# DO NOT EDIT THIS FILE
#
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub
#

### BEGIN /etc/grub.d/00_header ###
if [ -s $prefix/grubenv ]; then
  load_env
fi
if [ "${next_entry}" ] ; then
   set default="${next_entry}"
   set next_entry=
   save_env next_entry
   set boot_once=true
else
   set default="Arch Linux, with Linux linux
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"


When booting an error is displayed in loop and the only option is to reboot:

"fatal error: token too large, exceeds YYLMAX"
