Manually remounting > fixes it fine as far as I can tell. Do you use a custom initrd? The kernel usually mounts / ro at first and the initrd remounts it with `mount -o remount,rw /` later. You can also mount / rw from the beginning by specifying “rw” instead of “ro” on the kernel commandline¹. The current kernel commandline is visible in /proc/cmdline.
