Description of problem:
The grub.conf file can include a "password" command which can use "--encrypted" as an option. The documentation that comes in the grub RPM documents "password" but does not mention the "--encrypted" option. With RHEL 5.* there was no such option, it is new with RHEL 6.*
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. $ info -f grub.info -n password
Read the resulting text and see no mention of the --encrypted option.
Read the resulting text and see the --encrypted option mentioned.
If you want to see the --encrypted option try:
$ strings /boot/grub/stage2 | grep encrypted
password [--md5|--encrypted] PASSWD [FILE]
If used in the first section of a menu file, disable all interactive editing control (menu entry editor and command line). If the password PASSWD is entered, it loads the FILE as a new config file and restarts the GRUB Stage 2. If you omit the argument FILE, then GRUB just unlocks privileged instructions. You can also use it in the script section, in which case it will ask for the password, before continueing. The option --md5 tells GRUB that PASSWD is encrypted with md5crypt, --encrypted that PASSWD is encrypted (with algorithm specified in PASSWD: supported is md5, sha-256, sha-512).
