Original GitHub issue: https://github.com/netbootxyz/netboot.xyz/issues/1068

Describe the bug
Some of the Ubuntu releases have multipart squashfs files , e.g. https://github.com/netbootxyz/ubuntu-squash/releases/tag/20.04.3-9bc4558b when pulling the corresponding assets only the default file (filesystem.squashfs) is downloaded, but not the part2 file (filesystem.squashfs.part2). After changing the config file for ubuntu to look at the local server first booting fails. Manually downloading the part2 file (and possibly chown'ing it) fixes the broken boot.

To Reproduce
Pull all 3 assets for a ubuntu distro/flavour ( eg. 20.04, gnonme/default) and set the ipxe server as default server in the ubuntu config. Try to netboot that ubuntu version.

Expected behavior
The missing part2 file should be automatically downloaded when pulling the squashfs file

Screenshots

Additional context
Remote assets at version 2.0.54, run using the linuxserver docker image.
Manually downloading and placing the .part2 fixes this.
