I tries the testing enabled releng iso and created a FAT32 USB. It
boots successfully (in my system it was fs2:).

I was thinking about maybe implementing efistub + shell (like Archiso)
or efistub + rEFInd in AIF. I think its easy, just have this the same
loop in startup.nsh but this time launch the kernel with the user's
parameters. But I think for a HDD/SSD boot, rEFInd is better.

Regards.
