How full an OS is btx? The FreeBSD version in use at the moment is extremely minimalist. Essentially, everything that the new boot code can do without isn't there. The main constraint is the 8K of disk space available to the bootblocks, as the same version of btx hosts both the second and third stages of the bootstrap. However, a more capable version, that can (primitively) support its own edit/assemble/link development cycle, is waiting in the wings; and I guess /boot/loader may need additional facilities at some stage. -- Robert Nordier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
