But this will not mount /usr. At least it did not for me. |

To make it work you have to |
| 24 |
|
| 25 |
# echo "/usr" >> /etc/initramfs.mounts |
| 26 |
|
| 27 |
and recreate the ramdisk (genkernel ramdisk) |
| 28 |
|
| 29 |
I had to look into the code for that as this seems not to be documented |
| 30 |
anywhere. |
