Ok, since there are many ways to do it and documents such old, that |
| 33 |
are simply wrong (why not to remove that stuff): |
| 34 |
If possible: |
| 35 |
I want to reboot a new kernel with kexec and without systemd (I am |
| 36 |
using openrc). |
| 37 |
What document is recommended to read and to use? |
| 38 |
|

Thanks fpr any help in advance! |
