Subject: [Bug 1030085] [NEW] Password protected menu has incorrect
usage of the --users tag
To: <email address hidden>

Public bug reported:

At the page
https://help.ubuntu.com/community/Grub2/Passwords#Protecting_Menuentries,
Protecting Menuentries section there are following mistakes:

1. Adding Protection to Ubuntu Entries subsection
A piece of instruction reads

Add --users :

    printf "menuentry '${title}' ${CLASS} --users "" {\n" "${os}"
"${version}"

Actually it should be --users \"\"

2. Adding Protection to Other Entries subsection
Instructions in the box read:

sudo sed 's/--class os /--class os --users /' -i /etc/grub.d/30_os-
prober

I think --users should also be changed as in the section above (I did
not test this).
The thing is that in case of plain menuentry instruction (without
printf) --users "" work fine. But if there's printf in front of it the
actual menuentry is generated in grub.cfg  without those quotes. An
example of broken configuration is below:

menuentry 'Ubuntu, with Linux 3.2.0-27-generic-pae (recovery mode)'
--class ubuntu --class gnu-linux --class gnu --class os --users  {

This small issue actually broke my bootloader so I was not able to
quickly figure out what had happened.

Details about my installation as follows:

lsb_release -rd
Description:	Ubuntu 12.04 LTS
Release:	12.04
