Hello! I'm not sure where should I ask about new grub feature. Posing here.
I'd like to suggest grub simple user management to be able to unlock encrypted harddrives with user specific password. Currently to unlock encrypted harddisk you have to specify master encrypted LUKS key, and keep encrypted key on a harddrive to unlock it on second stage (kernel boot) or enter it manually second time. This can be done by grub it self with nice additional: unlocking by user name/password pair. User/password pairs can be stored in simple format (md5 sums for verification user input) and correct password can restore/decrypt master key (every user has it's own master key (which is equal for all users when decrypted) encrypted for its name), which solves all problems: decrypting master key with user name/password and passing master to kernel. Not important, but looks nice feature. Have nice day! -- AK
