The system I am testing has everything loaded into a ramdisk embedded into the kernel. I just boot up netbsd.test at the boot prompt to check it out. I'm also using crunchgen, which merges all the executeables together into one file, which is statically linked, so I shouldn't need the linker and the libraries.

My filesystem is listed below.

Root was readonly. So I copied mount and mount_ffs into /sbin and created a /etc/fstab with the following entries...

/dev/md0a / ffs rw 1 1
/dev/md0b none swap sw 0 0

After doing a "mount -u /" at the prompt, I was able to successfully change the root password. However, the system still drops to the prompt without a login after booting. What do I need to do to get to the login screen? Is this the function of the rc system?

Thanks in advance.
