yet. If you have xorriso and grub-mkrescue from GRUB 2 installed, then you can yet. You need the combination of a kernel and an initrd to boot Sortix. The
initrd is a root filesystem entirely in memory that is loaded by the bootloader
in addition to the kernel. You can generate the initrd in builds/ by running:
cd ~/sortix &&
make HOST=$SORTIX_PLATFORM initrd
If you want a copy of the kernel and initrd in the current directory (rather
than normally finding them in builds/ and sysroot/), you can run:
cd ~/sortix &&
make HOST=$SORTIX_PLATFORM sortix.bin sortix.initrd
You now have a sortix.bin and sortix.initrd pair. You can boot Sortix using a
multiboot bootloader by passing them as a multiboot kernel and multiboot
module/initrd.
