jffs2 image upgrade on running root

[Tony Hardie]

Hi Guys,
I have a running embedded 2.6.11 distro with a busybox type jffs2 rfs.
Not I am trying to upgrade that jffs2 imaged and tried something like to
following.

Have a temp ext2 ramdisk mounted in /mnt
pivot_root . oldroot
exec chroot . /linuxrc <dev/console >dev/console 2>&1
or
exec chroot . /sbin/init <dev/console >dev/console 2>&1

all "seem" to work bit init is still running I think on the /oldroot/ as
well so when I try to umount /oldroot is just get  device or resource
busy.
Any ideas?
