Unify Bootloader Configuration
|

=========
|
||||

||||
Unify bootloader configuration to support BIOS and UEFI boot at the same time.
|
||||
|
||||
Requirements
|

|
||||
None
|
||||
|
||||

----------------
|
||||
|
||||
Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
|
||||
|
||||
- name: AlmaLinux Generic Cloud
|
||||
hosts: all
|
||||
become: true
|
||||
|
||||
roles:
|
||||
- role: unified_boot
|
||||
when: is_unified_boot is defined
|
||||
- gencloud_guest
|
||||
- cleanup_vm
