Do you use a custom initrd? The kernel usually mounts / ro at first and |
| 13 |
the initrd remounts it with `mount -o remount,rw /` later. |
| 14 |
You can also mount / rw from the beginning by specifying “rw” instead of |
| 15 |
“ro” on the kernel commandline¹. The current kernel commandline is |
| 16 |
visible in /proc/cmdline. |
