Burg is a brand-new boot loader based on GRUB. It uses a new object format which allows it to be built in a wider range of OS. It also has a highly configurable menu system which works in both text and graphic mode. We did show you in a previous post how to install and configure burg in Ubuntu. Today we will see how to enable password protection in burg.
configure user and passwords
To add/edit user, use burg-adduser , for example :
sudo burg-adduser --super admin
sudo burg-adduser user1
The –super option is used to specify super user.
To remove user, use burg-deluser :
sudo burg-deluser user1
The password is stored in /etc/default/burg-passwd.
Setup GRUB_USERS variable in /etc/default/burg
Here is an example:
This means user1 can boot Ubuntu, no password is needed for Windows, user1 and user2 can boot other OS besides Ubuntu and Windows. Superusers can boot any OS and use system-wide hotkeys like `c’ to enter console mode.
Generate burg.cfg with update-burg
You can use burg-emu to check the configuration before reboot:
