This method was developed by Mike Montour (mmontour@iname.com) as an alternative to the full NFS-boot method described in the previous chapter. It's meant to simplify the process of configuring the server, and it also takes less space on the server (since it doesn't require the whole NetWinder disk image to be decompressed).
Mike has prepared a README for the use of his rescue filesystem. It is available at http://www.netwinder.org/~mmontour/. The NFS-rescue disk images are also available from the same place. Overall, the process is similar to that described in the previous chapter, `NFS booting'. Some of the differences include:
load-defaults setnetwork eth1 (or eth0) setenv kernconfig tftp setenv rootconfig nfs boot(It should get everything else over DHCP)
/exports/hdaN
by default.
Unpacking the tarball from the NFS host onto the local disk is also the
preferred installation method with my package (which now includes tar).
Notes for kernel 2.2.x and beyond: Upon booting you may encounter
the message `Unable to open initial console
' if using the older
rescue packages or disk images. If this happens, the solution is to create
a /dev/console
entry (major 5, minor 1) in your NFS image.
Alternatively, you can create a symbolic link from /dev/console
to
/dev/tty0
