This command specifies how the boot loader should be and supports the following options:
--timeout
:
Specifies the number of seconds before the
bootloader times out and boots the default option.
--append
:
Specifies kernel parameters.
These will be added to the syslinux
APPEND
or
grub
kernel command line.
The boot type is determined by the fstype of
the /boot
mountpoint.
If the fstype is "msdos" the boot type is
"pcbios", otherwise it is the fstype, which
is currently "efi" (more to be added later).
If the boot type is "efi", the image will
use grub
and has one
menuentry: "boot".
If the boot type is "pcbios", the image will use syslinux and has one menu label: "boot".
Future updates will implement more options. If you use anything that is not specifically supported, results can be unpredictable.
