Suport mount SMB/CIFS for live filesystem.squash instead of http download

[awsong]

I found that downloading live CDs to RAM is slow and sometimes not feasible if there is not enough RAM.

It should be easy to change the behavior to mount the squashfs location via SMB/CIFS.
I modified live-kali.ipxe and it works. Just need to setup samba server accordingly.

:kali-xfce-squash
set squash_url ${live_endpoint}/debian-squash/releases/download/2021.2-4237c18c/filesystem.squashfs
set kernel_url ${live_endpoint}/debian-squash/releases/download/2021.2-4237c18c/
set samba_share //192.168.1.52/public/development/netbootxyz/debian-squash/releases/download/2021.2-4237c18c/
set params components
goto boot

:boot
imgfree
kernel ${kernel_url}vmlinuz boot=live netboot=cifs nfsroot=${samba_share} nfsopts=user=guest ${params} initrd=initrd.magic ${cmdline} debug
initrd ${kernel_url}initrd
boot

Would you please consider adding this feature?

I usually download assets to local. But still, transport entire live CD on every boot is slow and it doesn't solve not-enough-RAM problem.
