The rest will work as intended.
Sounds rather confusing. This is how I see it: initrd=initrd.img.gz implies root=rootfs rdinit=/bin/sh is the special init=/bin/sh for initrd. Both initrd/root and rdinit/init must be separate for pivoting to succeed. If you want to drop into the initrd (i.e. rootfs), then instruct your initrd.img.gz not to pivot (i.e. not over-mount another filesystem).
