Syslinux is a functionally abandoned Legacy BIOS boot mode bootloader which has not seen updates since 2019, and is starting to see discussion amongst linux distributions to remove explicit support and packaging for Syslinux. Syslinux's relevance is also disappearing as UEFI booting is becoming the standard. While syslinux did go ahead and ensure their bootloader *could* be built and support UEFI, distributions also didn't uniformly adopt packaging and support for this bootloader. This change proposes to deprecate it and notates the areas in which functionality is deprecated. Change-Id: Ic52007fa4f207561d282eb5ae54273885c0ab0c0

deprecations:
|
|
- |
|
|
Support for the `syslinux <https://wiki.syslinux.org/wiki/index.php?title=Syslinux_6_Changelog#Changes_in_6.04>`_
|
|
and the often separately package `isolinux <https://wiki.syslinux.org/wiki/index.php?title=ISOLINUX>`_
|
|
and `pxelinux <https://wiki.syslinux.org/wiki/index.php?title=PXELINUX>`_.
|
|
Legacy BIOS boot loaders, is deprecated and will be removed the future.
|
|
This is for two reasons. The first is because it is a BIOS mode bootloader,
|
|
and the shift to UEFI booting has reduced the need for these packages.
|
|
The second reason is a lack of maintenance, which is ultimately the same
|
|
reason Linux distributions are discussing dropping support and packaging.
|
|
Syslinux has not been updated since `2019 <https://repo.or.cz/syslinux.git/shortlog>`_.
|
|
Incidently, the file format it utilizes *is* supported by Power hardware,
|
|
and that may result in the configuration template remaining in Ironic for
|
|
the forseeable future.
|
|
- Support for use of `pxelinux <https://wiki.syslinux.org/wiki/index.php?title=PXELINUX>`_
|
|
is deprecated due to the deprecation of support for Syslinux.
|
|
- Support for virtual media booting with x86 Hardware in Legacy BIOS mode is
|
|
deprecated due to the dependency upon
|
|
`isolinux <https://wiki.syslinux.org/wiki/index.php?title=ISOLINUX>`_
|
|
for use of Legacy BIOS boot mode. ``isolinux`` is from the ``syslinux``
|
|
package and source tree.
|
|
- Deprecation of ``pxelinux``, as a result of the deprecation of ``syslinux``,
|
|
does ultimately mean the default for the ``pxe`` boot_interface to carry
|
|
defaults for the use of grub based network booting, specifically for
|
|
for operators who are unable to use iPXE.
