Hi,
Just found few bugs in Console Security how-to located at
https://help.ubuntu.com/9.04/serverguide/C/console-security.html.
Bugs are related to GRUB Password Security how-to and affect all versions of
documentation.
1. First of all there should be a note that "password --md5 pass" string has
not to be located under the title item but in a global area.
2. The string "# lockalternative=false" confused me, it is necessary to note
that string has not to be copied without hash char. It has to be edited as "#
lockalternative=true" because it as a template for grub-update scripts.
3. !!!This is a major bug!!! After editing lockalternative to true it is
necessary to put "lock" parameter under the title with recover mode as follows:
title Ubuntu 9.04, kernel 2.6.xx-x-generic (recovery mode)
lock
uuid xxx
kernel /boot/vmlinuz-2.6.xx-x-generic root=UUID=xxx ro single
initrd /boot/initrd.img-2.6.xx-x-generic
4. !!!It is necessary to note, that lock parameter which has been added in the
item 3 will not be modified by grub-update script(in case of kernel upgrade and
other changes) because of "# lockalternative=true". Without "#
lockalternative=true" single user mode will be unlocked on next grub-update.
BTW, do we need to add lock parameter each time to the new title with a new
kernel?
