[syslinux] Password protection for the simple menu system

[H. Peter Anvin]

Hi all,

I'm looking at adding password protection to the simple menu system.  I 
have no plans to add password protection to the built-in CLI, however.

My current thinking is the following:

- Each entry can have a "menu passwd <blah>" where <blah> is a SHA-1 
encrypted & salted password.  Just "menu passwd" would password protect 
the entry using an "impossible" password, meaning that only the master 
password could unlock it.

- The menu as a whole can also, optionally, have "menu master passwd 
<blah>" which would:
   + allow any entry to be selected;
   + allow [Tab] to change the options;
   + allow [Esc] to return to the CLI.

Does that make sense to those of you that have asked for passwording?
