I edited rc.sysinit as root then on next boot the whole system is read only and can't re-edit it

Seams etc/rc.sysinit is linked to etc/rc.d/rc.sysinit

I tried chmod +rw and 777 still say read only file system

Any help appreciated

Thanks that worked. Can you explain? Was entire file system remounted a read write?

it seams that your root filesystem / was mounted read-only and the provided command remounted it read / write
