The 9boot program loads the kernel. The original Plan 9 9boot is driven by configuration variables in a plan9.ini file. Cinap's rewritten 9boot adds the capability of interactively changing configuration variables from the console before loading the kernel. That's really useful, especially when experimenting with new kernels or new hardware. But 9boot does not contain a shell or a built-in file system, so it doesn't allow you to type !rc and get an interactive shell. Once the kernel is loaded, the first thing it does is to execute the command /boot/boot from a small root filesystem which is built into the kernel. The main job of /boot/boot is to attach to the real root filesystem (on a local device or from a network server) and execute /$cputype/init to start the system. Historically the usual case is for /boot/boot to be a specialised program built from C source in /sys/src/9/boot. But it has always been possible to configure a kernel with a shell script as /boot/boot - see for example /sys/lib/sysconfig/ppc/boot for the PowerPC, or /sys/src/9/bcm/bootwifi.rc for a Raspberry Pi accessing its root file server via wifi. So, using a shell script as /boot/boot is not unique to 9front. But with 9front, it has become the default. This means there's always a shell inside the kernel, along with a few commands, ready to use interactively when !rc is invoked - after the kernel is loaded, but before the final root filesystem is attached. The kernel on the 9legacy install CD doesn't have a shell script as /boot/boot with the ability to invoke !rc. Perhaps it should. But that wouldn't have helped in this case. Yakku was stuck at the 'Boot from' prompt within /9boot, unable to find a kernel to boot. -- 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Tb5aaf646618a421a-M3a252d01292986d2f6699d46 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription

I misread the part about no kernel and thought we made it to the boot prompt and could not figure out the disk name.
