From 81d8dac5286fc0d2981df1a3284c184ae3c6e9d5 Mon Sep 17 00:00:00 2001 From: Reyk Floeter Date: Thu, 24 Nov 2016 07:58:56 +0000 Subject: Add support for booting the kernel from the disk image. This make the kernel/-k argument optional and, if not specified, tries to find the /bsd kernel in the primary hd0a partition of the first disk image itself. It doesn't support hd0a:/etc/boot.conf yet, and it is no BIOS or full boot loader, but it makes booting and handling of VMs a bit easier - booting an external kernel is still supported. The UFS file system code ufs.c is directly from libsa which is also used by the real boot loader. The code compiles with a few signedness warning which will be fixed separately.
