I understand that, but not why you need to run e2fsck before the |
19 |
switch_root. Is this to do with the way your system is set up? The object |
20 |
of the initramfs is only to get the system into a state where / can be |
21 |
mounted and switch_root run, I assume you are trying to do more than that |
22 |
with it. |
