You can simply remount /proc and /sys in the real root, just like is
done in the mountkernfs filesystem. However, you want to transition
/dev from the init root to the real root because that's where all the
device nodes have been created. In the script I attached before, this
is done just before run-init:
mount -o move /dev /sysroot/dev
In the udev bootscript, you probably want to make some things
conditional since they were already done from the initramfs: mounting
of /dev and copying of static devices. This is what I changed:
if ! mountpoint /dev >/dev/null 2>&1; then
if ! mount -n -t tmpfs tmpfs /dev -o mode=755; then
echo_failure
boot_mesg -n "FAILURE:\n\nCannot mount a tmpfs"
${FAILURE}
boot_mesg -n " onto /dev, this system will be
halted."
boot_mesg -n "\n\nAfter you press Enter, this
system"
boot_mesg -n " will be halted and powered off."
boot_mesg -n "\n\nPress Enter to continue..."
${INFO}
boot_mesg "" ${NORMAL}
read ENTER
/etc/rc.d/init.d/halt stop
fi
fi
and
# Copy static device nodes to /dev
for s in /lib/udev/devices/*; do
[ -e "/dev/${s##*/}" ] || cp -a $s /dev
done
