In general kexec itself hasn't really changed much recently. You load |
| 15 |
a kernel/etc, and then exec it. |

What may very well have changed is tools used by openrc and such to |
| 18 |
launch it. That guide obviously doesn't explain how to do it with |
| 19 |
systemd either. I'm pretty sure you just have to load your kernel at |
| 20 |
some point and then run systemctl kexec to shutdown and kexec the new |
| 21 |
kernel. I should probably do that more often. |
| 22 |
|
| 23 |
What I haven't gotten to work lately is a crash kernel. With all my |
| 24 |
btrfs panics of late it would sure be handy for troubleshooting... |
