Netboot and Remote file system

[izissise]

Hello,
I was wondering if there is any plans regarding supporting netboot with UKI,
especially with remote filesystems?

For example one could setup an http server containing the rootfs and mount
this rootfs using EFI_BLOCK_IO_PROTOCOL (ipxe can do it using sanboot)
the efi stub could then find EFI_BLOCK_IO_PROTOCOL devices and pass them to the kernel.
The user would end up with a net booted kernel with a remote filesystem.

UKIs should just work on uefi/http boots afaik. (but i didn't try that myself) you can build server info into the UKI (for example, include in the kernel cmdline field). The rootfs you can either also build into the UKI (if you have a lot of RAM or a small root fs), or you can transition into the rootfs on some network share, NFS, iscsi or so.
