I want to use pivot_root, so I don't use the special /linuxrc running
code. Instead I use "init=/linuxrc" as part of the command line. If
you do this your first script should work fine (pivot follwed by
chroot). But to be honest, I don't chroot. I don't think it's
necessary.
Using init=/linuxrc allows my first script to work.
However, it's a bit restrictive: if I want to override the usual boot
sequence and get the kernel to mount the real root and drop into a shell I
can't use this method. With the 'old-style' script, I can set
"init=/bin/bash". These get applied AFTER /linuxrc terminates. If I use
your method, I can't do that.
I realized yesterday that my second script works if I unmount /dev/hda2
before exiting /linuxrc.
Thanks,
Brian

Remember that any kernel command line options that the kernel doesn't
recognize get passed to init - as environment variables if they
contain a "=" and as command line arguments otherwise. So it's fairly
easy to invent a new parameter to control the "real" init and have
your linuxrc interpret it and act accordingly.
