I think you would need to
mount -uw /
u being for update.

It looks like your post describes single-user mode rather than safe mode.

When there is no /etc/fstab or the fstab is unworkable, you are put into
single-user mode with a prompt to enter full path to shell or Enter for
/bin/sh

Maybe you could create your boot media with /etc/fstab pointing to the
correct partition?
