Using local assets as cache

[shalak]

I think it would be great, to have the following workflow possible:

• on the first boot of e.g. ubuntu 22.04, its installer is downloaded from upstream, online source
• the download happens simultaneously to both the device being booted over PXE as well as the assets folder of netboot.xyz container
• any subsequent PXE boot will use the assets from local network, saving both bandwidth and time

From what I understand, this is currently impossible, and the only way is to either use the upstream, or local asset source, which needs to be populated before-hand.

could local and remote assets not be completely separate?

• when an image is selected to boot into, the system would check the local assets before pulling from the web
• if an image needs to get pulled from the web, it gets put into the local assets then sent from local to the device
• the next time that image is selected it would be run from the local copy right away

That's pretty much what I meant :)
