Instance Method Details

#assign_bootloader_device(selected_location) ⇒ Object (protected)

Set "boot_*" flags in the globals map according to the boot device selected with parameter selected_location. Only a single boot device can be selected with this function. The function cannot be used to set a custom boot device. It will always be deleted.

FIXME: `mbr_md is probably unneeded; AFA we can see, this decision is automatic anyway and perl-Bootloader should be able to make it without help from the user or the proposal.

Parameters:

  • selected_location (Symbol, Array) —

    symbol one of :boot, :root, :mbr, :extended, `none or Array with first value :custom and second device for custom devices
