If the attribute bootloader_console="serial" is set, the
expectation that there is no graphics hardware available is
valid. Thus the isolinux setup should not contain any ui
configuration instructions because that leads to run the
graphics initialization which blocks the system if not
present. Please note the bootloader_console allows for
multiple console configuration. In mixed setup the ui
configuration still applies. This Fixes#1153
Before this commit isolinux was used to boot an ISO and
thus forms a hard requirement. isolinux however only
exists for the x86 platform. This limitation did not
allow to create ISO images for other platforms. With this
commit a refactoring of the ISO boot setup is introduced.
* isolinux is only used if the bios firmware is requested
and the platform matches the x86 architecture. A runtime
check will check for this condition and exits early if
not applicable
* in case of the EFI firmware we already used grub in
EFI mode but still had isolinux in place for the legacy/CSM
boot. That part is now also replaced by a platform specific
grub eltorito image and grub's boot_hybrid.img for hybrid
boot. On platforms that do not provide those modules the
support for it will be skipped
With this change in place it's possible to control the ISO
boot layout through the firmware setup and all platform
specific modules are handled as such. Therefore we also
deleted the syslinux requirement. This Fixes#1092
grub2 is expecting the unicode font below the fonts
directory in the /boot/grub*/ depending on how the
distribution installs grub2. This Fixes bsc#1119416
This commit adds a new attribute called:
<type ... install_continue_on_timeout="true|false"/>
It allows to setup the boot timeout for install images
build with KIWI. If not set or set to 'true' the configured
boottimeout or its default applies to the install image
as it was before. If set to 'false' there will be no
timeout in the install image bootloader setup and the boot
only continues on manual intervention.
This patch is two fold. First part replaces the import of
dedicated video modules in the grub image by the all_video
module. Second part avoids runtime module insertion which
requires access to the boot filesystem which is not
guaranteed on sophisticated rootfs structures like btrfs
plus readonly snapshots and what not. Thus we make sure
all boot code is embedded into the grub image(s) and no
extra loading of modules at runtime will be needed.
This Fixes bsc#1096937
This commit adds the checkiso attribute in type tag, only available for
iso image types. Checkiso is boolean that determines the presence of0
a Mediacheck menu entry or not in the bootloader.
This patch is related to bsc#1049304
Depending on the distribution the grub tools are either named
grub2-tool or grub-tool. Additionally the grub configuration
data is expected to live in boot/grub2 or boot/grub. This commit
handles the tool calls and also the grub boot directory setup
in a generic way
If you want to boot an old snapshot, but not to do a rollback,
we need to tell the kernel which snapshot to use. This patch
also fixes the broken layout of the grub snapshot menu.
grub-snapshot.cfg should not be sourced at the begining, but
at the end of grub.cfg. Else with creating the first snapshot
this entry is getting the default boot target and the system
does not boot automatically anymore.
Generate a serial line setup for the isolinux.cfg file
according to the bootloader_console attribute from the
XML description. In addition delete the use of the obsolete
vga kernel parameter and work with the MENU RESOLUTION
ui configuration parameter instead
Some bootloader e.g grub supports graphics, text and also
serial consoles to hand over the output of the bootloader
menu. With this patch we allow to customize the console
used by the bootloader. So far only grub makes use of the
new attribute
<type ... bootloader_console="serial|console|gfxterm"/>

We can't expect that specific fonts to exist for all theme packages
in all distributions. The code here should rely only on theme.txt
In addition we check if any theme or font related data is found
in the legacy grub location boot/grub which imho should not be
used for grub2
An additional hidden entry allows the user to switch between the
graphics and the serial console by pressing the 't' key. The kiwi
grub2 template adds this switch if the terminal mode is set to
graphics. The additional entries are only effective of the
grub_platform is set to efi. Fixes#80
