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.
Kind regards, tastytea
