Update to syslinux 6 breaks TFTPboot

[John Stafford]

A major change was introduced to syslinux from version 4 to version 6. It introduced extra files as a requirement for PXE booting. See:

•http://www.syslinux.org/wiki/index.php/Library_modules

Debian jessie and sid are both using syslinux6 now. Ubuntu trusty is still using syslinux4.

Does this require changes in tripleo, or does it just need to be fixed in Ironic?

[Jon-Paul Sullivan (jonpaul-sullivan)]

This needs changes in tripleo.

The changes are to ensure that the correct packages are installed, and that the tftpboot area is correctly setup before being used by ironic.

I am not sure that there are any ironic changes needed, as once the tftpboot area is correctly setup, things just start working again.

I have a working patchset to upload to show this.

Perhpas we don't need change in the Ironic code but would be great to update the Ironic documentation to expose that difference between the syslinux versions

    Update installation guide for syslinux 6

    Fedora 21 and the next Ubuntu will have syslinux 6 in them. In syslinux
    6 modules are not "stand alone" as it was in versions prior to 4, see:
    http://www.syslinux.org/wiki/index.php/Library_modules

I guess fixing the docs is the only thing we can do on Ironic side
