A tiny bootloader bootstrap has been added to compile the builder-hex0 kernel from hex0 source. The boot compiler is builder-hex0-x86-stage1.hex0 and builder-hex0-x86-stage1.bin. The builder-hex0 kernel is now named builder-hex0-x86-stage2.hex0. The inclusion of a binary seed resolves the problem with the previous strategy which used an architecture-specific hex0 compiler. If sysb detects a full disk (i.e. DISK=sda) it now partitions the disk unconditionally because previously fdisk was reporting existing but empty partitions which resulted in no parititions being created. e2fsprogs is now built with --disable-tls because musl was built on Fiwix without full threading support and mkfs.ext4 was crashing without disabling thread local storage. kexec-linux writes the linux kernel and initramfs to a RAM drive on Fiwix which ensure a pre-allocated contiguous memory block. The following is written to the ram drive: a 32-bit number which is the size of the kernel in bytes, a 32-bit number which is the size of the initramfs in bytes, followed by the Linux kernel image, followed by the initramfs. kexec-fiwix invokes a sync syscall to ensure all writes are flushed to the ram drive and then initiates the kexec by shutting down Fiwix with a reboot syscall. Fiwix knows whether and how to perform the kexec based on kernel parameters passed to it.
