[Ltsp-discuss] Adding a menu at startup

[Ivaylo Ganchev]

Hello,

I have a couple of classrooms administered with LTSP. For one of them, I
would need to give a choice between more than one image at startup.

Is there a proper way to do that ? I looked at the
/srv/tftp/ltsp/i386/pxelinux.cfg/default config file and I think I can
tinker it a bit to fit my needs. Just wanted to ask is there a "canonical"
way to do this.

Thanks,

I'd recommend creating your pxelinux configs at the top-level tftp
dir(/srv/tftp), and copying all the relevent pxelinux.0 and other helper
files there. The create a /srv/tftp/pxelinux.cfg/default that uses the
kernel/initrd from /ltsp/* for each entry.

The tftp files at TFTPDIR/ltsp/* get autogenerated, and may clobber your
changes. While you can remove the pxelinux.cfg/default symlink in newer
versions and then edit pxelinux.cfg/default, it may be difficult to
select different images if they use a different kernel and/or initrd for
different images.


Good luck!

You may also consider looking a iPXE (ipxe.org). This allows you to create fairly robust menu systems.
