RPi ipv6 tftp boot

[MrHamel]

Description

Add RPi tftp boot booting to scale-network automation

Acceptance Criteria

Be able to build a VM with the necessary config files and packages to tftp boot a number of RPi's.

GitHub is picky about file extensions used when uploading files to issues.

exports.txt -> /etc/exports kea-dhcp4.conf.txt -> /etc/kea/kea-dhcp4.conf

It took me awhile to get to this due to physical therapy, lost my job, and prior arrangements. I have a complete image of "server5" so I can grab anything that is needed or share the partition image.

While making the image, I've learned the hard way that Clonezilla's use of partclone does not produce a loop mountable partition images by default even if it's RAW type. Luckily partclone.restore was able to remake the file into something that can be mounted with ease.

I'm currently in the process of xz compressing the sda3 raw partition file as I write this, and will upload it to my server at the colo for anyone who wishes to download it.

following up on this, are the individual server images posted anywhere? we need them right away if we are going to use them this year.

What is the expected outcome that resolves this issue?

Be able to build a VM with the necessary config files and packages to PXE boot a number of RPi's.

Server images meaning the RPi? They are files. I was lead to believe that another NFS rootfs was in the works for the RPi's?

If you're referring to sda3 partition of "server5", I dropped the ball on getting the image uploaded, it'll be available at https://ryanhamel.com/scale/sda3-ext4.raw.xz in 90 minutes (when the SCP will complete). File is ~22GB in size, going over a 40Mbit cable upload.

I can bring the server over to the convention center tomorrow afternoon, would be best to run off that for this year, and pick back up on virtualizing it after the conference. I have been making job hunting a much higher priority.

the new pi image did not get created, so we want to use the one from that server.

we could recreate that pi image withut too much hassle, but the initrd to boot from is more work.

I get 404 forbidden trying to download the large file

[MrHamel]

@davidelang Fixed and tested, was a permissions issue.

The other partitions to go along with it:

Below are the partition tables in various formats, really starting to regret not doing just a simple dd.

I am available to bring the server over to the convention center this afternoon, or hand it to someone before/after dinner.

Has there been any further progress on this? Is there a way we can make progress before the show?
