I was wondering if *anyone* has actually seen this work. I'm referring to |
| 19 |
booting a raid1 btrfs volume without performing a user-space device scan, |
| 20 |
using only the kernel `rootflags=device` setting. I have been struggling with |
| 21 |
this in various settings and am slowly starting to believe that this scenario |
| 22 |
is simply broken. |
