Details:

Recently I have seen this kind of line in grub.cfg:
menuentry 'Ubuntu, avec Linux 2.6.32-21-generic' --class ubuntu --class
gnu-linux --class gnu --class os {

It seem to be due to the script "/usr/lib/linux-boot-probe/mounted/40grub2"

# The double-quoted string is the title.
title="$(echo $@ | sed 's/.*"\(.*\)".*/\1/' | sed 's/://g')"

In fact this line work to isolate the final text of the 'menuentry' but
search for a double-quoted string

I try to correct this with adding a few lines in it just after.

----
# or in fact simple-quoted string ....
prime=${title:0:1}
if [ "$prime" = "'" ]; then
  title="$(echo $@ | sed "s/.*'\(.*\)'.*/\1/" | sed 's/://g')"
fi
------

I test if the result begin with a simple-quote, and if yes I reverse the
'sed' argument to isolate a simple-quoted string


So, the line in grub.cfg become :

menuentry "Ubuntu, avec Linux 2.6.32-21-generic" {


pay attention, I was obliged to use 'bash' instead of 'sh' for character
test.
Perhaps an equal solution can be found with 'sh'

Thanks, Alain
