Hi,
currently enabling booting via ipxe (https://ipxe.org/) over http needs
a dedicated mirror that has vmlinuz and initrd extracted from the iso.
Would it be possible to release those files - already extracted from the
iso - alongside those very isos?
This is something we should do, yes. I've created an internal ticket to look
into it (after failing to find the one I was *sure* already existed) -- I
personally am not very familiar with the relevant bits and pieces.
Wasn't that in the past already available and discoverable through
simplestreams for MAAS doing PXE boots?
Here an old example what I remember
https://lists.ubuntu.com/archives/ubuntu-server-bugs/2015-October/137272.html
IIRC this isn't used exactly the same way nowadays, but the following
still discovers me a set of kernels and can be further restricted as
needed:
sstream-query
http://images.maas.io/ephemeral-v3/stable/streams/v1/com.ubuntu.maas:stable:v3:download.json
kflavor=generic ftype=boot-kernel release=focal arch=amd64
sstream-query
http://images.maas.io/ephemeral-v3/stable/streams/v1/com.ubuntu.maas:stable:v3:download.json
kflavor=generic ftype=boot-initrd release=focal arch=amd64
The Maas team might have better info how to (or why you should not)
use those nowadays.
If this functionality exists through simplestreams, there should be a
note/documentation in the (cdimage) mirror page to the respective paths
in simplestreams to get those files via curl/wget - as those are on
most[1] distributions / busyboxes, and most[2] users might look on the
releases/cdimages.ubuntu.com domains first. So the work does not have to
be done twice, as it is already hosted somewhere else.
With all due respect to MAAS - I will have to stick to plain ipxe at the
moment.

[1] Just guessing - I've no actual numbers
[2] Still guessing - I've no actual numbers
[2] Person, that reads up on simplestreams now to try to use it with
ipxe. (Pointers/Hints are welcome ;) )
