This change reorganizes and cleanups our patches to reduce the patch number from 314 patches to 187. That's achieved by dropping patches that are later reverted and squashing fixes for earlier patches that introduced features. There are no code changes and the diff with upstream is the same before and after the cleanup. Having fewer patches makes easier to manage the patchset and also will ease to rebase them on top of the latest grub-2.04 release. Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

Subject: [PATCH] Make the menu entry users option argument to be optional
|
|
|
|
The --users option is used to restrict the access to specific menu entries
|
|
only to a set of users. But the option requires an argument to either be a
|
|
constant or a variable that has been set. So for example the following:
|
|
|
|
menuentry "May be run by superusers or users in $users" --users $users {
|
|
linux /vmlinuz
|
|
}
|
|
|
|
Would fail if $users is not defined and grub would discard the menu entry.
|
|
Instead, allow the --users option to have an optional argument and ignore
|
|
the option if the argument was not set.
