Subject: [PATCH 3/4] loader: suggest to install the right kernel devel package
|
|
|
0e54f6 |
|
|
|
0e54f6 |
Unfortunately, some package dependency system do not allow to make
|
|
|
0e54f6 |
sure that the kernel development package installed is the same version
|
|
|
0e54f6 |
as the running kernel. When this happen, the loader, unable to find
|
|
|
0e54f6 |
the kernel header, will suggest to rebuild the kernel with
|
|
|
0e54f6 |
CONFIG_IKHEADERS. For most users, this is probably not an option, but
|
|
|
0e54f6 |
installing the kernel development package corresponding to the running
|
|
|
0e54f6 |
kernel version is.
