Kindling Spark OS
Kindling Spark OS is a minimal read-only operating system image for NVIDIA GB10 boxes.
Kindling Spark OS runs beside a box's DGX OS and boots from GRUB. It gives models about 4 GB more memory by using a kernel with 64 KiB pages and utilizing the GPU display carveout. The image operates as an erofs file on the DGX OS disk, mounting read-only under a RAM overlay at every boot. It copies box identity, binds specific system directories, and imports DGX OS login users. Users log in with their existing passwords and group memberships. DGX OS remains installed as the rescue system to manage GRUB.
