Reducing the 3 passwords to login

[Jago25_98]

1) Password or at least, O/S selection at Grub menu

2) Password for HDD encryption

3) Password to logon.

What I really want is just one password to login. Ideally I'd like to pass this at the Grub stage so I can walk away and come back with it ready to use. But how can I do that?

You don't need a password at logon if you've got the hdd encrypted. Just have it autologin. You can't get to that point if you don't provide the encryption logon.

As far as grub goes, if you want a password, I think you'll need that one and the hdd encryption password. I don't have a password on grub, but I still have the selection menu, which is the default way grub works.

Can I get grub to pass a password to the HDD so I don't have to wait for the HDD pass to come up?

i have a random encrypted non-LVM swap via /etc/conf.d/dmcrypt
LVM rest of partitions with LUKS, so one password
and no grub password but it shows the choices of OS when it boots and i can choose sabayon or sabayon recovery
not sure how to autologin but i think i want that, maybe set the screensaver to lock if i dont log in within a certain time or something.
ANYWAYS i dont know if grub can store a prompted keyphrase and pass it but am interested if you find out how.
