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.
|
