Thank you for the great ideas. I'm running into an issue with the Redboot boot loader not accepting the kernel command line parameters I'm trying to pass. Apparently, it is an issue with the OpenWRT kernel. Additional details here [1].

I'm happy to try the option you mentioned about replacing /etc/preinit with something that performs a chroot or similar function but I'm a bit leary of doing so. If the script does not work, I'm unable to boot the old OpenWRT system or the potential debootstrapped system. Restoring proper boot to the board could be tricky. Do you have an example of how you'd do the /etc/preinit replacement? Maybe one could have a selection of booting OpenWRT or the chroot'ed environment?

Thank you again for your helpful thoughts!
